## Three-column layout

Starcat’s main window uses the familiar macOS three-column structure:

```
┌────────────┬─────────────────────┬──────────────────────┐
│  Sidebar   │  List + toolbar     │  Detail panel        │
│            │  Repo / Activity    │  README · metadata   │
└────────────┴─────────────────────┴──────────────────────┘
```

| Column | Role                                                                             | Docs                                                                             |
| ------ | -------------------------------------------------------------------------------- | -------------------------------------------------------------------------------- |
| Left   | Switch Manage / Discover / Activity; sub-entries for tags, collections, and more | [Sidebar](/main-interface/sidebar)                                               |
| Center | Repos or activity for the current category; page toolbar on top                  | [Repository list](/main-interface/repo-list), [Toolbar](/main-interface/toolbar) |
| Right  | README, tags, notes, AI, Health, and more for the selection                      | [Repository detail](/main-interface/repo-detail)                                 |

As the window narrows, the detail column may collapse or the list may take priority (actual behavior follows adaptive layout).

## Three top-level sidebar areas

| Area         | What it solves                                                                             |
| ------------ | ------------------------------------------------------------------------------------------ |
| **Manage**   | Organize Stars you already follow / knowledge base / tags / collections / Release timeline |
| **Discover** | Find projects not yet in your library (Trending, Weekly, Hot, and more)                    |
| **Activity** | Feed, announcements, subscribed Release stream, and related                                |

Discover modes: [Discover overview](/discover/explore/overview).

## Separate windows

Some capabilities work better pulled out beside the main window:

| Window          | How to open (common)                              | Docs                                           |
| --------------- | ------------------------------------------------- | ---------------------------------------------- |
| Repo AI         | Detail overlay → separate window; default **⇧⌘A** | [AI chat](/ai-features/chat)                   |
| RAG workspace   | Toolbar / default **⇧⌘K**                         | [RAG workspace](/knowledge-base/rag-workspace) |
| Agent workspace | Dedicated entry                                   | [Agent (Beta)](/agent-workspace/overview)      |
