This type of writing down ideas and half-thoughts is useful even if you work alone. Thoughts are very fleeting, the instant you put them to paper (or bits) they materialize and it becomes much easier to evolve them.
When doing deep work in some problem domain, often I find the brain starts to drop these highly ephemeral fragments of ideas (that are sometimes downright ingenious). Caveat is they often only come once, and then they're gone if you don't grab them.
I often keep an envelope or scrap paper next to my desk where I write down any idea I have, whether it's "I should fix this" or "what if I did that", really no matter how small I try to put it to paper.
What usually ends up happening is I somehow end up with a fairly concrete todo list of easy improvements.
I stuff those in my logBook nowadays - a single ascii text file. Started as you say with notes on random scraps of paper. To relieve my mind of carrying that burden, when I have something more pressing to do. But yeah these half-thoughts, intuits etc have showed useful over time? Some made it into TODO, and latter even into the DONE entries. Even if mostly their final destination is DONTDO. :-)
