I've been messing around with the main user interface for some time now, especially since the last few updates added some more information to the application itself. Personally, I think it's best when the interface is balanced and consistent. I opted for a full material-style redesign in the past, but I guess that's still a bridge too far (mockup of such a design: https://cloud.githubusercontent.com/assets/8352494/6771294/cca57a1c-d0db-11e...) . So far I've updated the connector (already released), and now I'm working on the data representation. See the included screenshot. There is a lot of room for other data, like for instance current ACC status, or maybe even a small voltage history graph, temperatures, or something like that. Ideas are welcome, even if they sounds like "keep it the way it was because I hate change" ;-)
