yep.
There is AquaTouch, my personal favourite. When I first got BTT i didn't use Aquatouch because it seemed too complicated, but when Yuuiko's recent update of Aquatouch came out, I started using it. it supports over 55 different apps and websites (i use it for netflix heaps, really handy) and its actually really easy to use. Also looks quite smooth.
There is my preset (which i dont even use lol) called the Future Preset. This is pretty much my customisation of GC.
There is the Caliguvara preset, which I've never used, but looks nice. the person who made this one has quite a few presets, i dont remember what the latest and most stable is....
Theres also heaps others. Have a look through the preset sharing category!
