I'm currently at somewhat similar place with my latest project good enough for my own usage to use but not really ready for public consumption because it's missing few important pieces. I've scratched my own itch and now I'm not sure whether I should keep scratching or just letting it tick as it is. I'm 80% done with it but I reckon that getting that last 20% would take at least double the time I've spent so far. Once in a while I get enthusiastic again about the project and resolve an issue or two and then think "why bother, it mostly works?" and forget about it. I've already picked all low hanging fruits and and I'm now reluctant to turn it into a job. I guess I could if I really believed that it's the next big thing but I'm pretty sure it's not so I let it just sit there. It's been a great learning experience though, good way to try out new stuff. It's also a great project to take code snippets from because I had to solve some things that I hadn't done before so there's that.
