Hey everyone... you're right. It's been way too long and we still don't have an Android version. Our focus has still been on iOS but mainly because each of the people on our small team have an iOS device. I'll do my best to make some progress here!
Thanks so much for the feedback, everyone! It's clear that an Android version is much needed. We're working on our 3.0 iOS release and then will immediately get back to the Android version. I promise... it's coming! Shooting for Spring 2015!
Sorting functionality will be a big part of the 3.0 update that we're working on now. It will be a free upgrade to all users. Thanks for the feedback!
