One little thing I noticed concerns the current assignment of the ESC key. It does (at least) two things
- Cancel edit mode
- Close card and return to noteboard
Since I do have to long-press in order to trigger 1., it happens that when you edit an open card, you accidentally trigger 2. directly after, which may be unintended. I think this behaviour could be improved by discarding the ESC event once the edit mode is cancelled, so that if you actually would want to close the card, you would need to release ESC and then press it again.
