Since VRChat has a method for users to insert their languages in a user profile, can it become a feature for world creators input what languages their creations support? With this in mind, the World tab/menu could have its own rows reserved for worlds that use the same languages you inserted into your profile to find others that speak your language.
Example 1: I am a world creator who has a world uploaded in English and Japanese. I want Japanese users to find this world, and I would like to tag my world so that it's listed that it supports both English and Japanese.
Example 2: I speak Japanese, and I want to find worlds that are supported by this language. Since my profile states that I selected Japanese as one of my languages, I want the World tab to help me find worlds that are tagged as this language.
