Not sure how hard it would be to implement, but it would be nice to have an option for skin uploads that didn't spam the live page, but one that doesn't leave them as drafts.

In my case it's because I like to share my older content, of which I have about 30 or so skins that could go public, but uploading all of them would spam the live page with older content and could overshadow other skins being released at the same time.
So having the option to upload a skin that would only be visible by the search bar, or one's profile/collections could be really useful for everyone.
