Desktop app: option for a compact sidebar (hide project group headers)

Feature request

The desktop app sidebar groups sessions under project-name headers. With many projects (30+), each project header plus its indented session row takes a lot of vertical space, and most groups contain only one session, so the header text is nearly a duplicate of the session name.

Request: a setting to render the sidebar as a compact flat list of session names only (no project group headers), or an option to collapse/hide the grouping. Similar to how the ChatGPT Codex desktop app lists chats as a single dense list.

Current workaround is Agent View (Ctrl+G) with collapsible groups, but that is a separate modal, not the main sidebar.

Environment: Claude Code desktop app, Windows 11.
