potting bench set up? how are you set up?

Hi All!
I wanted to know what you all keep on your potting bench and how you organize it. I use it for setting up my winter sowing flats and cuttings. My hubby built me a potting bench and now I'm trying to figure out what will be the best thing to outfit it with. I'm thinking of some sort of system for storing the potting soil underneath and maybe some other soil additives like sand, lava rock or peat. It's basically a tall little table 3x4ft. with a little shelf i set on top of it.
I'd love to hear how you guys have yours set up. This is a very basic set up. Just trying to streamline my process so i can do it throughout the day without a big set up and breakdown.
Thanks!
Lydia
