With the last update Tyme finally has full undo support. So if you accidentally deleted a project, stopped a timer or marked a whole year as paid. Undo to the rescue. And if you accidentally undid something that you didn't want to undo, you can even undo the undo using the redo (⇧⌘+Z) action.
Undo also works in the iPhone & iPad app (There is a new button in the settings to trigger the undo).
If we could we'd undo 2020, but just let's hope things will get better soon. Stay healthy!
