Data and permissions
Test mode
Try the app out without leaving rows behind that nobody wants.
The “Settings” screen has “Test mode”. While it is on, everything created from that moment is marked as test data, and the screen shows how many records have been created since.
One button clears them. The clearing is soft: the records move to “Recently deleted” on the data screen and can be restored.
The marking applies from the moment you switch it on. Records created before that are not test data and are left alone.
