I just spent 15-20 minutes meticulously creating a note, then in the process of trying to produce the highlighting effect I wanted, the note was unceremoniously deleted.
I need my note back.
Fwiw, attempting to edit the highlighting effect on a note SHOULD NOT have any impact on the existence or non-existence of the note itself.

Deleting a note should not be something that can be inadvertently done within the text space of the program, but only in the note window itself.
