# Tab Management

> Work with multiple documents in tabs across different panes.

Qualia uses a multi-pane tabbed interface. The workspace is divided into specialized pane areas, each containing tabs for different types of content.

## Pane layout

The workspace has four pane areas:

| Pane         | Location | Purpose                                    |
| ------------ | -------- | ------------------------------------------ |
| **Sidebar**  | Left     | Explorer, Search, Agents, Tasks, Knowledge |
| **Editor**   | Center   | Files, notebooks, terminals, settings      |
| **Terminal** | Bottom   | Dedicated terminal sessions                |
| **Chat**     | Right    | Conversation sessions                      |

Each pane area can hold multiple tabs. The terminal and chat panes auto-hide when empty.

## Tab types

| Type          | Content                                                                                      |
| ------------- | -------------------------------------------------------------------------------------------- |
| **File**      | Notebooks (`.ipynb`), writeups (`.qua`), text files                                          |
| **Image**     | The [image viewer](/notebooks#image-viewer) for plots, chat images, figures, and image files |

| **Chat**      | Conversations with Qualia                                                                    |
| **Tasks**     | Task DAG viewer (Gantt and graph views)                                                      |

| **Settings**  | Application settings                                                                         |
| **Search**    | Search results                                                                               |

## Working with tabs

### Opening tabs

* **Double-click** a file in the Files sidebar
* **Click** search results to open files
* **+** button in the editor tab bar opens the file creation dialog
* **Terminal icon** in the editor tab bar opens a new terminal

### Closing tabs

* Click the **X** on a tab
* **Cmd/Ctrl+W** closes the active tab

### Switching tabs

* Click any tab to make it active
* Use the sidebar icons to switch between sidebar views

### Reordering and moving tabs

* Drag tabs left or right to reorder them within a pane

## Editor splits

Work with multiple documents side by side in the editor pane.

### Creating a split

* **Drag a tab** toward the edge of the editor area
* A highlight shows where the split will appear — drop to create it

### Resizing splits

Drag the divider between split sections to resize them.

### Closing a split

When you close the last tab in a split section, it collapses automatically.

## Persistence

Open tabs are saved per workspace:

* Reopen Qualia and your tabs are restored
* Switch workspaces and each has its own tab state
* Tab positions and pane layout are preserved

Settings tabs are not persisted — they open fresh each time.

| Shortcut       | Action     |
