It looks nice but I wish there was a way to turn it off, takes too much time to go through all my cities now, was much easier with the smaller one. As an idea, maybe have this but make it like an internet browser in a way, have a little minus which minimizes it, the box button that makes it fill up your screen or shrink it down some, or the red x. Not sure if you understand but make it full screen but adjustable so it doesn't have to be in full screen, like an internet broswer.
Edit: Also there's a bug and I have no caves in any of my cities, just tan patch of hill which I have to hover over my mouse. If this isn't a bug, those spies sure are sneaky.
Edit Edit: I think I found my cave, I had to look really close but theres a tree in the way and I can only see the outline of my cave, it should be moved to the right a little more so you can actually see it. And keyboard shortcuts should be implented ASAP, keyboard shortcuts would be really nice if they were 2.6.1, too hard to navigate between islands and cities atm.
