I decided to start this thread for things that are possible with this phone through root, and the things we have done successfully and things that have bricked the phone. So here goes.
Things I have personally done:
Changed fonts via ROM toolbox
Installed xposed and busybox
Deleted bloatware apps - all metro bloatware, the stock launcher, Google play music etc.
Installed iPhone emoji via emoji font updater on the playstore
I also edited build.prop settings to allow haptic feedback when on vibrate or meeting profile.
Please keep adding to this list of things you or others have done successfully and things that have bricked yours/others phones.
Edit 2/8/14: I also found a few things that will boost performance, download andromizer and seeder, run seeder on aggressive mode and set it for start on boot.
Andromizer or andromizer pro, go to settings and force GPU rendering enabled, then to one touch kernel tweaks, (I screenshot every menu before I change them permanently or "apply (fix)" just so I can change back if needed) change the read ahead buffer size to 2048 for both then apply either fix or tmp, then back out and go to memory(RAM) Settings and change this to multi-process focus setting and apply, you can also enable the 3G/4G optimizer on all up -2(note this requires reboot and resetting all of the above if you selected tmp apply), after reboot go if done for 3G/4G optimization, go to tools and hit ROM Cleaner and hit start, this will clean up your phone quite a bit and this does require a reboot.
If any of this helped please don't be shy to hit the thanks button
