Layout Categories independent from the game category.
I understand that you can eventually find something other than a game. I'm really trying to help you. However....
As a user, it is not very evident that you can even see other categories. It's so diluted with games.
Having to click or tap on "games" to see other "categories besides games" is not very helpful, practical, or user friendly. This is other platforms biggest issue. Sure ppl stream 1000000000 games. But your missing out on other content and viewership that is not easily accessible to the user. So because a user cannot easily find a different category or subject of interest... non gaming streamers do not get views forcing them to another platform.
Gaming is gaming and will always be popular, but you platform can and will grow with other sources of streaming. But again, it has to be easily accessible.
There is no way as a new user (which I was at the time) would easily know to select "Gaming" to get to "NON Gaming Categories".
Thanks, I hope this helps!

Your example jpg illustrates your point. In the list of "top games" on the current mixer interface, "top game" #4 is Music.
At the absolute least, "top game" should be reworded to "top category".
I like your suggested categorisation and drilldown as a better longer term approach.
