@Jano: I don't have much time either, so when I see something that needs to be fixed, I open a reminder on GH (either for me or who wants to pick it up), so I don't forget about it
It's just a way to keep track of things and to describe them in "developer" words, not necessarily to fix them immediately. E.g. see issue #814.
As I'm getting old (:D) I forget things after 2 days, so it's a practice that works for me to compensate my brain load
