I just started using Car Dock Home v3 recently and I like it a lot. Its fairly customizable. I don't think it has any directional stuff built-in. Its functions more like a separate profile as you can add in any app, setting, or widget. You can use between 1 and 7 screens of apps and choose which page it starts on. It looks like you can even customize icon and grid sizes but I haven't played with that so I'm not certain. It can also turn the media volume all the way up when docked and put it back when its off the dock (which is nice sine the app I was using to do this before no longer works since the GB update). I did notice one bug so far in that with the Pandora widget, if after you initially launch it, and before the song data shows up in the widget, pressing on the widget causes it to ask if you want to remove the widget. Once a new song starts to play, the widget updates and it works normally, but still an issue that needs to be resolved. In all, I'm fairly pleased.
