Abit version 1.0-beta16 is out now.
There are still a few bugs, but an annoying one with the floating action button is resolved.
Also, there is an experimental progress bar for the proof of work (sending message) notification. It's mostly fake, but should give the user some sense of progress and the time to be expected. Due to the way POW works, a proper progress indicator is not possible.
