I've been thinking of writing some desktop software to carry out a specific task. Tho I'm not exactly sure what to write (what would catch on and be popular) as most stuff have already been done before. So I am reaching out to the community for ideas in what you think would be a hit in software. Also keep in mind i'm an indie developer, so it cannot be something extremely complex (I code by myself other wards). It also can be cross platform Windows/Unix/OS X.
