I was just wishing there were adjustable shelves in one of my upper kitchen cabinets. I want to put a big utensil jar in one of them. I don't like utensil jars on the counter because the lesser used utensils will gather dust. It's more convenient to have them a bit above my head than in a lower cabinet, plus hot air rises so I like food to be down below. But there's not enough height in the upper cabinets because of the three shelves. I wish I could remove the middle shelf.
Maybe keep only the frequently-used utensils in the jar on the counter and put the others "flat" into a pull-out drawer?
