The application seems very cute and handy and it still might be very useful in a lot of specific use cases. Just keep in mind that it might not be production ready for you.
As for the open issues, 140 are feature suggestions, and 36 are currently classified as bugs. I'm hoping to start popping the list of bugs soon after I'm back home from my vacation which will be soon (am typing this from the airport waiting to board!)
Don't burn yourself out. This is some really good software and we need you around to maintain it :)
