Description

Adds collapse on drag to the app sidebar. Dragging it below 15px will collapse the sidebar. While collapsed, hovering over the left edge shows a resize cursor and a tooltip. Clicking or dragging will now reopens the sidebar

Problem

The sidebar had a minimum width of 220px and to Collapse the sidebar completely either click on title-bar button or keyboard shortcut. Once collapsed, the drag handle disappeared, making it impossible to reopen it by dragging.

Fix

  • Updated sidebar dragging to collapse below 150px and reopen when dragged back, while preserving the previous width.
  • On drag release, saves the final state using toggleSidebarCollapse and localStorage, checking the latest store state to avoid conflicts.
  • Added a 3px movement tolerance so clicking the collapsed handle reopens the sidebar.
  • The collapsed handle stays visible with a resize cursor and a 4px offset from the window edge.
  • Added a theme-aware "Show sidebar" tooltip with the configured keyboard shortcut, visible only when collapsed.
  • Updated styles in Sidebar/StyledWrapper.js and added e2e tests for dragging, clicking, and tooltip behavior.

Fix the comment typos and remove the duplicate comment.

Lines 86-87 contain "faild" and "consdier". They also say the same thing twice. Keep one timeless comment that states the reason.

Proposed fix
-      // click will faild to open the sidebar if pointer moves a bit on click. It will be consdier as drag
-      // Until the pointer has moved a few pixels from where it was pressed, treat it as a click (not a drag)
+      // Small pointer jitter during a click must not count as a drag, or the click would fail to reopen the sidebar
