Since I've updated to the Lion GM, my old BT-client (Vuze) didn't work anymore.
Thank god it didn't, since that's why I found out about Transmission; I love it and it's 10 times faster than Vuze!
One ideal feature would be the synchronization of preferences across your Macs via iCloud; this way you don't have to change everything at all your Macs. Also, your total ratio could be calculated by the upload/download stats of both your Macs.
Thoughts?
