I haven't tried sending files, and I came from the stock KK.
EDIT: Also, are there any fixes in the latest build?
Build 36 [2014-11-22]:
CM 11 kernel with dt2w
I forgot to remove the commit that broke sensors of the fix above will have to be used again for screen rotate etc
BT pairs but I couldn't get a photo to send from Carbon to LP on the GPe, not sure what side the error is on but probably Still in Carbon
