The modal Working Tree Changes dialog becomes a persistent panel in an end-side AdwOverlaySplitView (Ctrl+Shift+D): files grouped by directory with +N/-N in the diff colours, the existing reader pushed inside it, and the panel following the active workspace. Breakpoints are reordered because only the last matching one applies.
