After changing Paranoid Settings > User Interface > Workspace UI > Phablet mode the setting still show as Phone mode (UI changed to Phablet) after rebooting.

Doesn't allow you to apply back to Phone mode unless you toggle to something else (To bring up the apple button) then back to phone mode.

Gallery crashes when taking panorama (Intermittent)

Phone crashes when turning on wifi hotspot (Not sure if that was what you meant in hackfest bugs)

But probably already known issues.

Great release, seems faster than ICS build 11 for apex launcher.

Not sure how to properly submit the bugs, hope it helps.
