The motivation here is to create SRS flashcards that would work well in Anki. Often, the exact text from the note is not very suitable for a flashcard, however each flashcard is directly tied to a note. So to change the flashcard, you have to change the note.
First I thought about making flashcards and notes separate but synced entities, but that’s probably too complex. A simpler method is letting us hide notes.
This way, I can create a note, customize it to read just how I want to see the flashcard, then hide it so it won’t appear in outline/mind map/exports - because a good flashcard doesn’t necessarily make a good note and it’s just clutter that duplicates an already existing note. It would only appear as a flashcard in Review, and also in a new window to be accessed by a new menu option like “Show list of hidden notes”.
