Somewhat similar to the "let us skip battle animations faster" thing - you know when you move a unit in a FoW enabled game and it takes a second after the unit stops moving to update your FoW-cleared zones, preventing you from performing any other action while it does so? This is quite a minor thing, but the slowness of this makes FoW games feel somewhat clunky and sluggish. Perhaps it should be made faster, or just update in real-time.
Yeah I have the same request. I keep clicking to hope it speeds up just a little. It's getting a bit annoying.
