It took quite some time but now a new release of Yaaic is available!
Yaaic 1.0 features a new revamped UI looking more like a modern Ice Cream Sandwich / Jelly Bean Android app. Swiping through channels is much smoother thanks to the ViewPager component that replaced the old ConversationGallery. At the top is now a new indicator replacing the dots at the bottom. The indicator uses 2 colors to indicate the state of conversations currently not visible: Blue channels have unread messages waiting and yellow channels are indicating that there's a highlighted message waiting for you.
