Split panes & Tabs

Nearly everything in Octarine is a tab. Notes, Graph View, and Ask Octarine all open as tabs instead of individual entities, enabling a flexible multi-document workspace with both horizontal and vertical split pane layouts.

Tab Types and States

Each tab in Octarine has specific properties that define its behavior:

• Focused tab: The tab you're currently editing or interacting with. Only one tab can be focused at a time across all panes. Identified by an accent-colored border at the top
• Active tab: Each pane has one active tab - the currently visible tab in that pane. Shows a grey border on top when not focused
• Dirty tab: Temporary tabs opened from the file tree, calendar, or meta sidebar links. These tabs are replaced when opening another file the same way. Identified by italic title text and a dot beside the name
  • To make a dirty tab permanent: right-click and select Protect from Replacement or start typing in the editor
  • Tabs opened via Cmd/Ctrl + P, Cmd/Ctrl + T, doclinks, or Open in new tab are permanent by default

Creating and Managing Panes

Split your workspace to view multiple documents simultaneously:

• Horizontal split: Cmd/Ctrl + \ - Splits the current tab horizontally
• Vertical split: Cmd/Ctrl + Shift + \ - Splits the current tab vertically
• Move tabs between panes:
  • Drag tabs directly from one pane to another
  • Right-click a tab and use Split (duplicates to new pane) or Move (transfers between panes)
• Pane navigation: Each pane includes Back/Forward buttons that maintain a history of viewed tabs

Tab Operations

Working with tabs within each pane:

• New tab: Cmd/Ctrl + T - Opens a new empty tab in the current pane
• Cycle tabs: Cmd/Ctrl + Tab - Cycles through all tabs in the current pane
• Jump to tab: Cmd/Ctrl + [1-9] - Jumps directly to a numbered tab position
• Close tab: Cmd/Ctrl + W - Closes the current tab
• Reorder tabs: Drag tab headers horizontally within a pane to rearrange

Navigation History

Each pane maintains its own navigation history:

• Back button: Returns to the previously viewed tab in that pane
• Forward button: Moves forward through the navigation history
• Closed tab recovery: Closing a tab and pressing Back will restore it

All the navigation options are also available via the Cmd/Ctrl + K bar.
