On the Mac
Every pane is a real tmux pane rendered in a native window. Split horizontally or vertically, resize by dragging, reorder panes, and spread sessions across as many windows as you like. Agents keep running inside tmux regardless of what the windows are doing.
Layouts persist per project
Each project folder remembers its workbench: the split arrangement, open file tabs, browser tabs and sidebar state. It's saved automatically as you work and restored the next time you open that folder — no "save layout" button to remember.
On the iPhone
The phone live-mirrors the Mac's layout: the same panes, tiled the same way, updating as the arrangement changes. Tap a pane to focus and type into it, and split panes right from the phone. Resizing and reordering are done on the Mac — the mirror follows instantly.
Viewing another Mac
A Mac can also be the remote viewer for another Mac. In that case the viewer keeps its own layout per remote folder — browser tabs and split arrangement — stored locally on the viewing machine, so your setup at the desk and on the laptop can differ without fighting each other.
