- Replace the branch badge with a compact count badge; recolor the
folder name and badge to sidebar-primary on a tinted row background
when expanded
- Lighten the selected conversation item background so the expanded
folder row stays the strongest signal
- Add a "+" button on each folder header that reuses a single new-
conversation tab across folders, disconnecting the old ACP session
so the connection lifecycle reconnects against the target folder's
working directory
- Align conversation guide line and status icon to the folder chevron center (left: 0.875rem)
- Use fixed 1px guide line with darker shade (sidebar-primary/15) for better visibility
- Add bottom border to sidebar title and a top gap above the folder list
- Tighten list horizontal padding to px-2 with matching pt-2 for consistency
- Fill the done status icon frame directly to avoid sub-pixel off-centering
Replace flat/grouped view toggle with a show-completed filter dropdown,
add expand/collapse-all control, extract status icon component, and
simplify the sidebar header.
