When there wasn't a search feature, this category was useful for searching avatars by their initial, but currently, it takes up space on the marketplace that could be used by some of the styles that aren't currently featured (like realistic or fashion), it also is a very easy to game category that takes away attention from others (previously there were avatars whose title started with special characters to show up at the top, and after it was no longer allowed, avatars that start with a number or with the word 'Avatar' are starting to show up).

My suggestion would be to remove this section and add an alphabetic sorting option to the "New" category, which also helps with redundancy since that would be the main and only place to see all avatars in the shop.
