Scavenging material should have the same readout at the bottom right as any other harvested material. If you click on a metal deposit you get a nice bar at the bottom right with the mining difficulty and the amount. Yet scavenge is relegated to a tiny box with tiny hard to read text.
When in the Management screen, a second click on a selected tab should close the screen and go back to the map. I don't know how many times I've done this, thinking it would close the screen, but it doesn't. It should.
I would kill for a custom pointer that changed shape and color depending on which mode you were in. Move in white, build road a tiny bulldozer, traffic lights a, er, tiny traffic light, etc etc. Something where there would be no mistaking what mode you were in. Again, about 8% of my clicks are backing out of a mode I didn't know I was in.
More as I think of it while playing.
