I've always hated corner cabinets, and the lazy suzan is slightly better than useless. I once saw a video of a commercial corner cabinet that had drawers and I was instantly convinced that drawers would be immensely more useful. After getting permission from the boss, I set off to retrofit my cabinet with drawers.
Truth be told, I got more than I bargained for. Construction of the drawers turned out to be significantly more difficult that I had imagined.
