The new FAB store can be overwhelming due to the amount of content. Browsing categories is still difficult because
Often content is not properly categorized, or overlaps, i.e. stylized default style and low poly - simplest mesh content. Or you find content you discard but the seller has dozens of offers. Thus the new search option to hide specific sellers is a good way to clean the search, though it can still be challenging.
Yesterday, I spent perhaps 40 minutes removing publishers from the sale view for characters, low poly and fantasy and then the website displayed an error message. After refresh the configured search was gone.
Other issues
Some publishers can not be hidden, I suspect those which have less then 3 letters in the first name
Some content is wrongly categorized, i.e. sci-fi under fantasy
Some content does not fit category, i.e. characters cat displays static mesh content
