Just my $.02.
Building cabinet doors to cover my peg board / small shelf area. Just simple 1x3 frame and 3/8 plywood with a piano hinge. That way, I can close the doors when not in use, and no one sees the tools. One section for air tools, one for wood working, one for body work, one for welding. I use the rollaway for hand tools, wrenches, etc.
