Just got my Tesla console installed yesterday at my local Service Center. Looks nice. I have not actually used it for any cups or much of anything else yet, but I can already see that it could be improved. Since the cup holders are configurable (in a way I did not realize until I had it in my car) and removable, the thought I have is that Tesla should supply one or two pieces to act as "walls" or barriers between the space used for storage and the space for cupholders. The wall pieces could be slid into the same slots used for the cup holders. That way, if a person wanted to set up a certain part of the console for storage, stuff in that area would not slide down into the space around the cups. As it is, I see the potential for annoyance when stuff slides around. E.g., small items like a finger clipper or ear buds or coins or any number of things would be much easier to contain if there was a separator for them.
I may try to fashion some walls myself (but they won't look as nice as I'd like or match the console materials).
