I emailed this to the given address, but I'm posting it here too, so maybe other can confirm:
A possible bug:
In the android system setting I use network provided time, 24-hour format, GMT+2 timezone. Albeit in the system setting I see the correct time, the clock in the launcher is off by 6 hours. (The date is correct.)
A GUI suggestion:
If you are in the 'main menu' (games/apps/store/sideloaded/etc) the bottom part of the screen shows you button mappings that are not currently working. Maybe they should be faded/greyed out until you make your selection.
