That's what happens when you don't monetize your projects, you never find the time to add the features you'd want to, because the initial enthusiasm has worn off.
It looks nice btw :)
Actually though it was an experiment for me using Backbone and Mongo, so I wasn't sure it was even going to hang around very long, but it's been a useful tool for me as it is so I haven't felt the need to make any real changes to it.
Plus at this point, since I haven't promoted it at all I'm the only person who's using it so I'm not super motivated to work on it.
This is where I like Google Play market more, where you don't have to take risks. You can just buy the app, and if you don't like it, you can get a refund. Apple should have done that a long time ago.
