By the way, what I hate about most of the note-taking apps is they usually require or push you to give every note a title. C'mon, people, do you invent a title for every note you would write on a paper or a sticky?
The same is relevant to e-mail subjects: i many cases the subject is wide, volatile or plain lacking. It often happens the actual contents of an email I receive has nothing to do with what's there in the subject field.
I share your frustration. However, it makes sense, if you think about it. Having to give a note a title makes you think it through, and with Zettelkasten you can easily split it into many atomic notes, each covering their own thing.
As a workaround, you can have one note dedicated to all your random notes, which you can periodically review and reorganize.
