@LaFayette A wake up all seems logical, as a player would probably at some point forget what units are inactive. I would suggest an old school bell icon. It would implying "attention", "alarm", "wake-up" etc.
I look forward to test this feature I hope and wonder if it works so well that old/new players would chose to always run through all their units one by one this way, as it is convenient and easy. There is no doubt that I would like to use it as I sometimes forget a unit here and there. But it really needs to be easy, simple and intuitive.
Does the screen center on a unit/territory automatically when pressing next?
Maybe there should be an option where players can select if the system controls next/prev/center/sleep of individual units or intire territories?
