 - **StatusBarView** — Connection status indicator, active task display
 - **ListSettingsModalView** — edits list name, working dir, default commit type, and per-list Model/SystemPrompt/AgentPath. Opened via context menu or gear button on a list row.
+- **RepoImportModalView** — bulk-creates lists from git repos discovered under chosen parent folders. Opened via the folder button beside "New list" in the Lists island, or the "Add repos as lists…" Help-menu item. Repos already wired to a list show as disabled/"(already added)".
 - **DetailsIslandView** — contains an "Agent settings (overrides)" expander with per-task Model/SystemPrompt/AgentPath, showing inherited effective values. Disabled while task is running.
 
 All views use compiled bindings (`x:DataType`).
