Tabs

A diagram is not a single canvas. It is a collection of tabs, each its own independent board with its own elements, layout, theme, and background. New diagrams start with one empty tab, and you add more whenever a piece of work deserves its own space. The tab bar sits along the bottom of the editor, and the active tab fills the canvas area above it.

What a tab is

Each tab is a self-contained canvas inside the diagram. A tab carries its own elements, its own theme and background pattern, and an optional lock state, all independent of the other tabs around it. Common ways people split work across tabs:

• An Overview tab with the high-level picture, and detail tabs behind it.
• One tab per system, team, or phase of a project.
• A scratch tab for ideas you are not ready to file yet.

Tabs are ordered, and you can drag them to reorder them in the bar. The + button adds a new empty tab and switches to it.

Naming and reordering tabs

Tabs start with default names like Tab 1 and Tab 2, and you can rename any of them:

• Double-click a tab label to edit it inline. Enter commits, Escape cancels.
• The same rename action lives in each tab's right-click or ellipsis menu.
• Auto-rename on first edit: while a tab still has its default name, editing the label of its first element renames the tab to match. This only happens once, so later edits leave a renamed tab alone.

Drag a tab to a new position to reorder it. Reordering only moves the tab in the list, it never touches the content on any tab.

More with tabs

Each tab also carries its own menu of actions, covered in their own guides:

• Tab Folders group related tabs under a named, collapsible chip so a long tab bar stays readable.
• Linking Across Tabs turns any element into a jump point to another tab.
• Add a Tab to Another Diagram copies a tab into a different diagram.
• Importing and Exporting move a tab's contents in and out as a file.
• Cleaning Up a Tab tidies a tab's layout in one click.
