ᐅ How can I optimize the storage space in the IKEA Metod base cabinet?

I have been thinking for some time about how to best optimize the storage space in my IKEA Metod base cabinet. The dimensions are fairly standardized, but I feel that even with shelves or the standard drawers, the space is often used below its potential. Specifically, I am interested in which organizational systems, material utilizations, or additions I can use inside the base cabinet to make the most efficient use of the space for my kitchen appliances, supplies, and smaller items without compromising accessibility or stability. Perhaps someone has experience with custom inserts or alternatives like modular boxes that fit perfectly within the Metod frames. I look forward to tips, ideas, and also advice on mistakes to avoid.
