The third thing was support. A page for supporting the studio appeared.
There are three prices, and supporters get a wallpaper. You can buy without signing in. Payments aren't ready yet, so for now the page only shows the prices.
Since money is involved, I opened a refund policy along with it, and a page crediting the licenses of the open-source artwork used on the homepage.
There is one small thing on the account side too. The account deletion screen now tells you that deleting your account also removes what you bought. I wanted to make sure nobody is surprised after deleting.
