Haven't tried your A and B builds yet as the previous version is now running so well for me. I will definitely update should you get to a Cornerstone public release though.
If you need any more beta testers for Cornerstone, I'm happy to get involved. As a fairly "noob" user, if it can be broken, I may be just the guy to try and break it - LOL!
One question (which may illustrate what I mean) Is there any way to get the bottom button bar to autohide. I found a checkbox under the settings to autohide when running full screen apps but it seems to make no difference. When I start Asphalt 6 (legit paid for "Play Store" dl) the home/back buttons just refuse to go away and the only app which it seems to partially work with is the Aldiko eReader where the buttons are visible when I open it but if I tap to pull up the reader options and then return to normal reading mode, the bar will disappear.
Not trying to hijack the thread - If I'm being stupid just call me stupid - I can take the shame!!
Thanks again for this ROM. It still makes me smile when I use the tablet and every time I whip out my Touchpad in public (no smutty innuendo intended) the iPad and ChiPad brigades crowd around to see and generally slink away admitting that "No, their tablet can't quite do all that".
