Question / Feature Request: Keep right sidebar closed by default

Hello,

Is there currently a way to keep the right sidebar (details panel) closed when opening issues, milestones, etc.?

Right now, the sidebar automatically opens every time an item is clicked, and even if I close it, it does not remember the state.

If this is not currently possible, I’d like to suggest a feature request:

**Feature suggestion**

- Add an option to keep the sidebar closed by default
- Or remember the last state (open/closed) per user or session

**Why this would help**

- Reduces visual clutter
- Improves focus when navigating between items
- Gives users more control over the UI behavior

Thanks!
