Was just online and people are sure talking about the change to radar! Some like it and some don't <shrug>. One even thinks the clipboard map looks more cluttered now.

The popup field info box works well, and with the fieldnames fading out now I find I'm spending more time with the map zoomed out - I'm getting the big picture of what's going on in game across the whole map.
On my in-game screen, the shading appears darker than the screenshot you've posted. I'm running default graphics options with gamma at defautl (1.0?) I think the lighter shading in your screenshot looks better.
Is there any way to make the shaded circles not additive? One concern I heard is when the radar coverage from two adjacent bases overlap, if both have radar out (shading=red), the additive nature of the shading makes it harder to see the red dar bars against the shaded area.
