What's the PR

• Fix BUG: Preview Image Size Issue in Preview Panel #3653
• Add additional file extensions that will be displayed at maximum size in the preview panel.

Comment

• This is something we've postponed before, but we really should make it user-configurable. For now, since it's a hassle to implement, let's just go with this...

Poem

In the warren of code, new formats appear,
Now .m4a and .mov hop in with cheer!
.heic and .flv, .webm join the spree,
Previews grow larger—what a sight to see!
A rabbit’s delight, more files to explore,
With each extension, Flow Launches more!

352-356: Use a HashSet for faster extension lookups
Replacing the array with a HashSet<string> (using StringComparer.OrdinalIgnoreCase) yields O(1) containment checks and will scale better as you add more extensions.

-private static readonly string[] MediaExtensions = 
-{
-    ".jpg", ".png", ".avi", ".mkv", ".bmp", ".gif", ".wmv", ".mp3", ".flac", ".mp4",
-    ".m4a", ".m4v", ".heic", ".mov", ".flv", ".webm"
-};
+private static readonly HashSet<string> MediaExtensions = new(StringComparer.OrdinalIgnoreCase)
+{
+    ".jpg", ".png", ".avi", ".mkv", ".bmp", ".gif", ".wmv", ".mp3", ".flac", ".mp4",
+    ".m4a", ".m4v", ".heic", ".mov", ".flv", ".webm"
+};

352-356: Add unit tests for new media types
There are currently no tests verifying that IsMedia recognizes .m4a, .m4v, .heic, .mov, .flv, and .webm. Please add coverage to prevent regressions.

Let me know if you’d like a test scaffold.

---

352-356: Consider externalizing the extension list
A hard-coded array makes updates and user customization harder. In the future, moving these values into plugin settings or a JSON config would be more flexible.

---

352-356: Sort extensions alphabetically for maintainability
Alphabetical order improves readability when the list grows.

-    ".jpg", ".png", ".avi", /*...*/, ".flv", ".webm"
+    ".avi", ".bmp", ".flac", /*...*/, ".mkv", ".webm"

---

352-356: Verify coverage of other common formats
Formats like .wav, .ogg, or .webp aren’t included. If preview support is desired for those, consider adding them now.
