There are many threads on this forum suggesting that Valve add things like custom word censor lists, the ability to hide all Early Access games from the store, ignoring entire tags, or most bafflingly (because this implies they already found the page and changed settings on it), removing pornography from the store.

All of these are features Steam already has and has had for a long time, and all of them are accessed via clicking on your username in the top right, then clicking Store Preferences.

There are also a few places in the Steam Client settings that link directly to the store preferences. The Store tab in the client settings contains nothing but seven different links to the store preferences page. The Friends & Chat tab contains another link. Searching for games on the store links to the store preferences with some yellow text explaining what can be changed.

But somehow, that's not enough. People still have no idea that these features exist, as evidenced by these features constantly being suggested despite already existing. And honestly, I don't know how you'd solve that. But I feel like it does need to be solved in some way.
