At the moment, the Avatar Marketplace is being forced down everybody's throats whether they like it or not.
While this was somewhat alleviated by allowing people to keep "My Avatars" the default option on their Avatars tab in the Main Menu (as opposed to its prior setting which defaulted to the Explore tab), it is still being pushed way too much, especially for those who have no interest in it.
A very prominent example for me is the "Explore Avatars" button in the avatar list. I do not want to use the Avatar Marketplace, give me a way to turn that button off. It is unnecessary UI clutter for a feature I never want to use. I purchase my avatars' source files because it means I can actually use the files in Unity and Substance Painter, unlike the Avatar Marketplace which is just a "get rich quick" scheme for your company with minimal effort.
