In general, I think there’s quite some updates that could be made to the Data section and App Data.
There’s an edit column in App Data to the left. When you click the pen you get the popup "modify an existing data base entry.
Reason for change, simplification:
When your DB grows, the view gets kind of cluttered. When you’ve found what you need to edit, you have to scroll back all the way to the left, press the pen and edit the field cell. This is quite the operation to change a cell.
Why not implement a direct edit function in App Data through double click? I.e. single click, highlight cell. Double click, edit cell.
