I would like the devs to give us the option to remove the default sandals from our player models when nothing is equipped or when we are wearing the emperor's new boots. I can see this being achieved either through a setting or by adding a new footgear glam.
It would also be nice if we had a painted toenails glam similar to false nails for consistency. I personally can't use any fingernails glams together with open-toed footwear because I dont like the inconsistency. The feet look much better in the game thanks to the 7.0 graphics update so I feel like this is something they should consider and hope that they can explore adding barefoot glams in the future.
