:LOL that pic is pretty funny.
I'm thinking if he just throws stuff up in there you don't have much chance of keeping it organized! :LOL
But my thoughts: it looks like a lot of wasted headspace in that cabinet...maybe you could trade cabinets w something else? I have mine in a cabinet w three shelves, and then I have 3 turntables (lazy susans, whatever) that I bought to go in there; one small, one large, and a med one that has two tiers. And the spices are alphabetized, or else I would never find what I need.
One way to simplify would be to not buy dried herbs and grow your own. Herbs are super easy to grow and taste 5000% better than dried. I grow basil, oregano, rosemary, sage, fennel, marjoram, chives, garlic chives, parsley, cilantro, etc. This will clear up space in your cabinet; you get the added joy (and aroma) of caring for the plants; and the difference in the food is amazing. You can buy herbs already started in pots at Home Depot if you have one for a less than $2 (and they have a great selection), or more like $4 if you have to go to Lowe's.
