Add Frequently Accessed Tags
Twitch is very useful as a platform for language immersion, but when you're looking in categories you need to enter a search for your target language as a tag every single time. While trending tags in categories makes it very easy to add tags in one click (most of which are pretty redundant, e.g. "Multiplayer" is one of the trending tags for Fall Guys), tags which you frequently enter need to be put in every single time.
This would also be a useful feature for people who enjoy speedrunning streams.
