Well Adam, you're ofcourse correct and i agree with you on that. A fully customizable UI is the optimal solution but it needs to be based on something that people like alot and feel familiar and comfy with that won't get in the way of their workflow too much. So if you pick the best most juicy parts from each of these apps UI's and then blend that into one UI that people like then you should in theory have a winner (knock on wood).
