A cool idea on using the space of the corner cabinet ! With these shelves, you can organize, see what's in it and not have to get down on your hands and knees if there was a lazy Susan in the space. Down side--- no hide and seek space.
Key storage- door at the end of a kitchen cabinet for small storage. This gave me the idea that the inside of a cabinet door should be painted with chaulkboard paint so you can keep notes or grocery list there.
