Multi-Pane Layouts

Split one window into dual, tri, quad — or more — panes and move files between them.

Adding and removing panes#

Press ] to add a pane and [ to remove one. Close the focused pane with W. There’s no fixed limit — add as many panes as your monitor can comfortably fit.

Moving files between panes#

Drag files directly from one pane to another, or cut with X in one pane and paste with V in another. Each pane keeps its own history, so navigating in one never disturbs the rest.

Resizing#

Every region of the window is resizable — the sidebar, each content pane, and the preview pane. Grab any divider and drag.

Saved with your workspace#

Your pane layout is part of workspace restoration: quit Cosmil and reopen it, and every window comes back with the same panes, tabs, and active directories.
