Thanks for the files! Well... any change to the UI will take some time to even start, since I'd rather give priority to known bugs. My first intention, however, is to read hildon style guidelines and try to adhere better to them, implementing also the ability to start typing contact name to scroll down to that particular chat. That should speed up things a bit. The two pane option, if implemented, will not be splitted by type of conversation, but just as a 2xN matrix so that twice the information is available at the same time. Some of the minor changes will be implemented when possible
