Given a question on math.SE, I may or may not participate in the discussion. But, there might be some thought processes and ideas about the question (or the subsequent discussion), which I would like to make note of. A note, typically would be like this:
Ah! look at the parity of the $n$-dimensional integer lattice and apply pigeon-hole
slightly polished version of question xyz, nothing noteworthy
This helps when I go to a post I have posted long back or when I digging out for something specific among my favorites.
I am looking for an app/script/functionality(?) which stores all the notes(either locally or on a server). I should be able to navigate to the question from the note. When I open a question page, all my note(s) of that page should appear in a dropdown or sidebar or some mechanism. Although, I have found the necessity of this only on math.SE, please do suggest generic solutions.
PS for Mods: I am not sure this is the best place to post it. If it belongs to stackapps or something else, let me know and I will delete this and post this there.
