This one would be a lot of effort, but I thought I'd throw it out there as a QoL feature, but I'm envisioning a system where you can select what forums your most interested in and everything you don't select will be removed from the "recent content" tab. For example, I like to follow switch, 3ds, and PC stuff, but I'm not interested in politics, playstation, or Wii. Let me select those somewhere and then my "recent" feed will contain more things that I am interested in. You could even just add this in as another one of tabs already existent so the current method would still work perfectly fine.
