Saving Your Work
Auto-save:
your work is automatically saved to this browser. Closing the tab and reopening BreakBox restores exactly where you left off.
📁 Sessions
opens the session manager where you can save, name, rename, load, and delete multiple sessions.
Click the session pill in the bottom-left status bar to jump straight to the session manager.
The dot turns yellow when you have unsaved changes since the last named save, and pulses cyan briefly each time auto-save writes.
Sharing & Backup
💾 Export
downloads the current session as a
.box
file (JSON) you can share or back up.
📂 Import
loads any
.box
file into the current session.
Sessions in the browser are tied to this browser on this device — use Export if you want to move work elsewhere.
