Make the app more user-friendly
What you have right now is a great start but I feel like some important features are missing. As a new user, I find the app confusing, disorienting, and a little overwhelming when you look at it. I don't recall if there was a "Getting started" tutorial when I started Twitch for the first time, but if there isn't - there should be. Also, I'd really love and appreciate a way to view my user profile. As it stands I don't find it easy unless I type in a URL to do so, which is fine, but most programs have features like this.
As for the main page that pops up, perhaps revamping it to where it shows my profile picture, then streamers I follow (maybe thumbnail clips of recent streams below), and then showing my recent streams and such would be awesome. And then adding a line for featured somewhere in all that would be good I think. Would also give you the chance to create a little feature line for, "New Streamers" so they could get some love too.
I also did not expect that my stream dashboard (and many other features) would be completely separate from the app. That was really weird. It's not awful but just weird as I was expecting to access most of my functions and features within the app, not on a webpage. It feels a little clunky this way to me but I can manage.
The Creator Camp is a fantastic idea and has been helping me learn about a lot of the weird and new things twitch has to offer. So please keep working on that, it's awesome and I love the videos. I felt like a child stumbling around trying to figure things out at first until I found this.
