Describe the feature

The Issue:
Right now, the sidebar is always visible, which takes up screen space that could be used to show more photos — especially on smaller screens or in fullscreen mode.

Suggestion
Add a collapse/expand toggle button (like the chevron in Notion or VS Code) at the top of the sidebar so users can:

Hide the sidebar to see more images at once

• Keep it accessible via icons + hover tooltips when collapsed
• Have their preference saved between app restarts

Why it’s a good fit

Better gallery experience: More space = bigger thumbnails, less scrolling
Low effort: Uses existing tools (Lucide icons, Radix tooltips, Tauri store)
No breaking changes: Pure frontend tweak (~50 lines)
User control: People can choose what works for their screen
This is a small change with a noticeable improvement in daily use. Would you be open to this? I’d be happy to raise a PR!
