I definitely second this. It was very hard to tell the difference between my vehicles and the ground because of that. Some pixelation is probably fine, and the game's aesthetic is great, but maybe a screen filter or smth would be easier on the eyes than pixelation. If the game looked half as clear as that final screenshot does, it would be 100x better. Imagine being able to visually see ERA detonate or a shot ricochet, rather than just being a bunch of vague pixels.
Also, I don't know if this will help anyone, but use ctrl + left click in order to order your units to move backwards. I don't know if you can chain reverse and forward gears in the same line, but it would be a cool feature.
edit: also, a mode that lets you switch between infantry view and tank view would be good in order to see what pathways your tanks/infantry can take at a glance, without needing to dismount first.
