Small useful project ideas?
I'm looking for some ideas for a small software project to work on; specifically, things that would be immediately useful to people here.
Emphasis on "small", though - I'm thinking of the kind of project that would be close to feature-complete after its first release, like utilities and monitoring tools and such. Naturally, the result would be open-source as usual
(EDIT: Things like "WHMCS modules" aren't really an option, though. I'd most likely be writing it in Node.js or, if the project warrants it, try my hand at doing it in Rust.)
