[Ovmsdev] Thoughts on iPhone 5 and its larger display

[felix bonnier]

Do we have any new or "extra" info that would be of interest that the screen has been too crowded for until now?  notably the top view screen maybe we can redistribute the info a little on that screen……?  I'll try to take a look at that over the weekend

But, fixed screens like the Battery and Car will take some work to think about and take advantage of that new usable screen real estate.
