Just tried it out, froze up on me and I couldn't exit it because it took over my phone and I couldn't access any other programs to terminate it.
Overall it seems polished for what is there, but at the same time there is a lot of stuff lacking (like customization.. and I'm not talking complete overhall, just something as simple as changing some options of the way it operates)
Trying to uninstall it now, will probably watch this to see if improvements are made.
edit: also the scrolling is not intuitive and none of my hardware buttons work when inside the app which really defeats the purpose of having something like this
