I feel like it's hard to use the app in important settings, since there's no way to backup the tasks. It would be very helpful. Thanks!

A plain text output/export would be OK although export as a .csv file, to import into Excel and similar, would be better. I have had a few glitches where editing a card goes awry and it is infuriating to lose the info so periodic backup is good or, better, being able to periodically export everything in the app to a spreadsheet as backup please
