The update adds a tray-menu setting to hide the viewer toolbar and uses cursor position to control toolbar visibility. It also changes image viewer tooltips and metadata display, updates PDF loading and rendering, makes plugin matching asynchronous, adjusts video matching, adds localized strings, adds a project package reference, and validates version tags.
Changes: Hide toolbar
Layer / File(s)
Summary
Toolbar setting and tray control QuickLook/ViewerWindow.Properties.cs, QuickLook/ViewerWindow.Actions.cs, QuickLook/TrayIconManager.cs, QuickLook/Translations.config, OPTIONS.md
ViewerWindow stores the HideToolbar setting. The tray menu toggles the setting and shows its checked state. Localized labels and the option documentation are added.
Toolbar visibility and appearance QuickLook/ViewerWindow.xaml.cs, QuickLook/ViewerWindow.xaml, QuickLook.Common/Styles/MainWindowStyles*.xaml
ViewerWindow checks cursor position to show or hide the toolbar, guards toolbar animations against overlap, and applies theme-specific backgrounds to the titlebar-overlap spacer.
Image viewer tooltips and metadata
Layer / File(s)
Summary
Localized tooltips and metadata display QuickLook.Plugin/QuickLook.Plugin.ImageViewer/ImagePanel.xaml, QuickLook.Plugin/QuickLook.Plugin.ImageViewer/ImagePanel.xaml.cs, QuickLook.Plugin/QuickLook.Plugin.ImageViewer/Translations.config
Image viewer controls use translated tooltips. The metadata tooltip displays EXIF content with width and height entries first, followed by other entries.
PDF loading and rendering
Layer / File(s)
Summary
Document wrapper and page access QuickLook.Plugin/QuickLook.Plugin.PDFViewer/PdfDocumentWrapper.cs, QuickLook.Plugin/QuickLook.Plugin.PDFViewer/PdfPageExtension.cs
The wrapper supports path- and stream-backed documents, cached page information, refresh, and synchronized disposal. Rendering helpers use its page-size accessor and shared render lock.
PDF preparation and asynchronous rendering QuickLook.Plugin/QuickLook.Plugin.PDFViewer/Plugin.cs, QuickLook.Plugin/QuickLook.Plugin.PDFViewer/PdfViewerControl.xaml*, QuickLook.Plugin/QuickLook.Plugin.PDFViewer/AsyncPageToThumbnailConverter.cs
The plugin reuses prepared document wrappers. PdfViewerControl loads wrappers and renders pages asynchronously, applying results only when the request and document remain current. Thumbnail conversion renders in a background task.
Asynchronous preview selection
Layer / File(s)
Summary
Preview request and plugin matching QuickLook/ViewWindowManager.cs, QuickLook/ViewerWindow.Actions.cs
Preview requests unload the current plugin, show a loading window, serialize plugin matching, and discard stale requests before displaying a match.
Video plugin matching QuickLook.Plugin/QuickLook.Plugin.VideoViewer/Plugin.cs
The video plugin priority changes, directories are rejected, and MediaInfo probing occurs only for existing files.
Project and version updates
Layer / File(s)
Summary
Package reference and version fallback QuickLook/QuickLook.csproj, Scripts/update-version.ps1
The project adds System.Resources.Extensions version 8.0.0 with private assets. The script replaces tags outside the supported numeric format with 0.0.0.0.

Pinning a preview while a plugin match is pending can leave the pinned window stuck in its loading state. Turning Hide Toolbar off can leave the window controls invisible. PDF preview refresh, page rendering and thumbnails have edge-case failures. The toolbar timer, cursor zones and version script also have open issues. Fix the pin and caption problems and confirm PDF stream ownership before merging.

Explanation
The title "Add an optional auto-hiding toolbar" matches the main change in the changeset. The PR adds a HideToolbar option (off by default) that hides the viewer toolbar when the pointer leaves it and shows it when the pointer nears the top of the window. The tray menu gets a Hide Toolbar item, and OPTIONS.md documents the new option. The title is concise, specific, and free of noise. The other changes (instant preview loading, asynchronous PDF thumbnails, video plugin priority, metadata tooltips, version script fallback) are secondary and not named in the title, which is acceptable.

Stop the timer when the window closes.
The timer starts for every preview, including previews with HideToolbar disabled. Neither Close() nor QuickLook/ViewerWindow.Actions.cs, Line 514–519, stops it. An active DispatcherTimer retains the object whose method handles Tick. Closed windows therefore remain reachable and continue receiving ticks. Repeated previews accumulate retained window trees and timer callbacks. Stop the timer and detach the handler on Closed. (learn.microsoft.com)

Recheck hiding after the pointer leaves the keep-visible zone.
When HideToolbar is false and both plugin titlebar flags are true, this return can leave the caption visible indefinitely. Reveal the caption while the pointer is over it, then move into the lower preview area. The completion callback has already returned. Later mouse moves call ShowToolbar(), which rejects opacity above 0.01. The timer and caption-leave handler also return because HideToolbar is false.
Schedule another visibility check when the pointer leaves the zone, including for plugin-controlled auto-hide.

Clear the held hide animation when hiding is disabled on window reuse.
After a toolbar hide completes, the caption opacity stays at 0 because the hide storyboard uses HoldEnd. When the user disables hiding and previews again, BeginShow updates HideToolbar but leaves that animation in place. ShowToolbar then returns early because both HideToolbar and TitlebarAutoHide are false. The caption and its window controls stay invisible until the window is recreated.
Clear the opacity animation on windowCaptionContainer when BeginShow finds both hiding modes disabled. Also reset _toolbarAnimationRunning, because FinishToolbarAnimation may not run after the animation is removed.

Restrict both cursor zones to the viewer bounds.
If the pointer is above the window, GetPointerY() is negative and both zone predicates return true. Horizontal position is also ignored. The timer therefore reveals the toolbar when the pointer is outside the viewer and can keep it visible indefinitely.
Check the pointer against the viewer’s horizontal bounds and require a nonnegative relative Y before applying either height threshold.

Convert the pointer offset to DIPs before comparing heights.
This subtraction produces a screen-pixel offset, but ActualHeight uses device-independent units. The comparison therefore changes with display scaling. (learn.microsoft.com)
At 200% scaling with ActualHeight equal to 600, a pointer 200 DIPs below the origin produces approximately 400 here. The reveal threshold is only 210, so a pointer inside the intended reveal zone does not reveal the toolbar. Convert the screen point into window-relative WPF coordinates before testing the thresholds.

Reject numeric values outside the assembly-version range.
If an untagged checkout has an all-digit abbreviated hash such as 1234567, the regex accepts it. The script then writes it as the assembly version, but its component exceeds the allowed maximum. The build fails instead of using the fallback. Validate each component before accepting $tag. (git-scm.com)

Show the preview window at once in a busy state and resolve the matching
plugin in the background, so slow plugin probing no longer leaves the
window blank. Each request carries an id, so a stale match cannot replace
a newer preview.
Ported from the same branch:
- PDF: asynchronous page thumbnails
- Video: lower plugin priority so cheap viewers are tried first
- Video: skip directory paths without probing MediaInfo
The toolbar and ImageViewer tooltip changes of that branch are left out:
master already has newer implementations of both.

Do not dispose the old document while the replacement uses the same stream.
For a stream-backed document, Refresh loads newDocument from PdfStream and then disposes oldDocument. The document takes ownership of the stream it is given. Disposing the old document can therefore close PdfStream while the new document still depends on it. Rendering on the new document can then fail, because PDFium reads page data from the stream on demand. A later refresh that resets PdfStream.Position can also fail on the closed stream.
Give each PdfDocument its own stream. For example, keep the source bytes in the wrapper and create a new MemoryStream for each document, instead of passing PdfStream directly to PdfDocument.Load. Apply the same change to the constructor path that loads the first document.

Notify PdfDocumentWrapper when LoadPdf replaces it.
The thumbnail MultiBinding reads PdfDocumentWrapper (PdfViewerControl.xaml:63). LoadPdf replaces that property without raising PropertyChanged, so a thumbnail binding can keep the previous wrapper. Plugin.cs reloads the same _pdfControl, so this path is reachable. A reused thumbnail may then render from the disposed document and show the loading placeholder.
Raise the notification after the assignment so that bound thumbnails re-read the current wrapper:

Restore the caption when Hide Toolbar turns off.
When the hide storyboard completes, its opacity animation holds windowCaptionContainer.Opacity at 0. Setting HideToolbar to false removes only the trigger value. The held animation still applies. For a plugin with ContextObject.TitlebarAutoHide == false, ShowToolbar returns at its guard, and the other toolbar handlers also return early. The caption controls can then stay hidden until a later show animation runs.
The same transition occurs in BeginShow (ViewerWindow.Actions.cs:297) and BeginLoading (ViewerWindow.Actions.cs:410). Handle it in the setter so both call sites are covered.

Keep the pending preview associated with its original window.
When InvokePreviewWithOption receives pin, it starts matching and then calls ForgetCurrentWindow at Line 146. That method replaces _viewerWindow with a new, hidden window. When matching completes, this visibility check discards the result. The pinned window remains busy without a plugin.
Track the target window and request lifetime together. Allow a pending pinned preview to finish on its original window, independently of subsequent previews.
