Noticing frustrating bits and lack of better options is a habit, I believe, which has to be developed. It's easier to notice horribly frustrating things and that's what startups often do, but that might be out of scope for many side projects. However, noticing small things that might be fixed in an evening or a week - that's a habit. I find it similar to the 'I want to blog, don't know what to write' issue.
