I'm still disappointed LibreOffice 4.0 didn't come with an overhauled and more modern interface. It looks like an UI from 2000.
Rumors say they might launch an Android version this year, or sometime next year. I really hope they at least won't disappoint there, and take full advantage of Google's Holo/card UI for tablets and phones. At least on PC's they might've had an excuse that being open source they didn't have good designers, but on Android they have no excuse. All they need to do is use Google's UI resources, and build their UI with those.
If I were them, I'd wait until the launch of Android 5.0, tough, as I think that will come with a pretty overhauled UI, too, and might be better to fully optimize LibreOffice after that, and also be compatible with it.
