That was, yes. Which is why I was confused when you wrote "always found this odd in CortUI". :)
The point is, it should be consistent across all UI objects on the same screen mode. (Changed the ticket description to reflect that.)
My idea was (and of course we can discuss that if you disagree) that on flight mode, all windows should keep a minimum margin to the screen border, so that these 'here's more you can't see right now' icons are always visible, which -- with the status bars -- is about 35px. In theory, I'd also like their labels to be visible, but then we're up to 100px or so and the windows basically clutter the middle of screen, which is worse than cluttering the 'out of visible area' icons (which we desperately need to give a name, so I can stop referring to them in long quoted terms).
That's different from map mode, where these icons just don't exist. If you zoom in a lot on the map, you will just miss what's outside the visible area. That's how the map works and changing it would be a code change. So there we can use that extra space to make more room in the middle, which is the most important area of the map mode.
