I think it was Admiral(?) who beat you to asking for this one, and it hasn't been there all that long (maybe since 1.009, not sure).
Aye, it was I who asked for it, and he who quickly implemented it.
I had also asked something about scaling, simply because the icon sizes never change, so big things (e.g., home planet command base for the enemy) make small icons look like they're "moving" as you zoom.
I can deal with it, though; I understand the problems.
Cheers!
