ESC to save is unusual but convenient. Except when I accidentally delete something and ESC to cancel immediately, just as i do in any other editing dialog.
In any case, undo function is absolutely necessary.
I use CN for event logging. When I filter the notes by tags and get the result, sometimes I also want to know what happened right before and after the focused one. That is what I mean about "context".
But in the current version, for this purpose, I must double click the note, copy some text from the focused note, then select "all", then search for the text, then select the note for the second time, then ESC for the second time.
Or, simply remember the title and scroll for it in all notes view.
It's so......
Is there any cleverer way?
