First off, it's awesome that you decided to turn this into a ROM. This will allow you to tinker with the little details and such that wasn't possible with the "hack" method before. I can't wait to see what comes of this.
Secondly, I'm just wondering if you changed Gtalk? It's pretty unusable in tablet mode which is why I'm hesitant to switch over to this right now.
Thirdly, this is just a blind request and I'm sure you have tons of other things on your plate, but is it possible to flip the nav bar around? So instead of having the navigation keys on the far left, have them on the right and the notification panel/clock on the left.
Anyways, again, awesome stuff you're doing. Keep it up.
