Hi Sharkie,
I installed the CHT2.0 beta on top of your 6.5 ROM two days ago, and it's running very well. I've had no major (and very few minor) problems with it. It seems to be very stable. I've had no crashes.
Personally, I don't like the look of the bottom bar and it's very blah icons, but hopefully it's skinnable. (Yes, I know it can be disabled.) I'm also not thrilled with the icon options. I was hoping it would allow more functionality. I tried to use one of the Custom options with my favorite program, but the icon showed as a white square.
Yeah, I know ... it's beta.
I like that when you switch pages the entire contents move, not just the quicklinks. However, that and the new bottom bar seem to be the only really big changes to CHT. Frankly, I was expecting something more dramatic. But overall, I'm happy with CHT2.0.
