The ROM features the following:
Built daily from CyanogenMod 10 source.
Tablet UI independent of DPI.
Tablet UI can be toggled.
Custom DPI settings.
Settings menu reflects Tablet or Phablet modes.
Modified Trebuchet launcher for Tablet UI layout on the Nexus 7.
Expand desktop power menu option (now exported to CM10).
Clear all recent apps button.
Extra spaces in launcher dock for Phablet UI.
Goomanager hooks for notifications and incremental updates.
I will consider feature suggestions, but will only implement those which I feel enhance the tablet experience.

To install, wipe the caches if coming from CM10, do a factory reset if coming from another ROM, flash with the latest JB gapps from goo.im, and enjoy.
