I just installed Ubuntu Touch of my Asus Nexus 7 (2013 Wifi), it seems to run all fine but I've got a few questions:

• Is there an update available to latest Ubuntu Touch or is the Legacy version the only version?
• How can one turn it into a single app device, like launch browser in full screen mode on boot - I want to use it as a wall mounted tabled to control my openhab installation
• Is it possible to support double tap screen to wake-up?
