Restore…

Screen: Deploy · the History panel.

What it is

In History: asks to restore this version. Only the person who holds the edit sees it.

Press it.

Opens Restore version N? It is saved as a new version. Nothing is deleted. The house does not change until Save & Deploy.

House and app: this control writes nothing to the project by itself, so nothing changes in the house or the app from it alone.

Save or cancel your changes first — a restore would replace them.
