Undoing the last change
Before every change the editor saves a copy of your app. Click “Undo” in the top bar to return the app to how it was before the last change.
Hover over the button to see a description of the last change before undoing it. You can click more than once to go back step by step.
Note: The editor keeps the last ten changes in the current session only. If you reload or close the page, earlier changes can't be undone. But you can always ask in the chat to bring something back the way it was, or restore a saved version from “Versions”.
Code export
Your app is real files. Click “Export code” to download them all in one zip file. Export is available on the Pro and Business plans.
This helps if you want to keep a copy, or hand the app to a developer to continue it.
