Allow for Text or even Extension Panels, in certain cases, to have a dropdown option.
Basically, instead of having an X amount of panels or extensions active with no option to either hide the text unless someone wants to see it, profiles can seem cumbersome or sometimes even downright copied off of some big streamer. Not only would dropdown options help declutter profiles, but it would also help to increase the creativity that someone may have because they'll infer that anyone who is willing to open a panel, for example, and read what's inside, is someone worth either following or communicating with, while also granting more options for people to speak or share information that is sincere or funny or whatever it is without the initial first impression showing either a lot of "clutter" or that the streamer seems a type of way before a potential follower, or dare I say, potential friend, even gives a streamer a shot because their profile may not match their ideal candidates. This would also help to save space on the site visually. It would open the door to other customizations, similarly to Markdown, that may allow for a varied group of fonts or colors that better blend into the aesthetic of the streamer.
If a streamer doesn't care for this feature, then they keep moving forward, because it really isn't that controversial of an addition. But, for those who do care, it could change their whole demeanor on how to better focus on their streaming and less on things like their profile. Especially since profiles can be viewed while the streamer is offline. This would help people, and negate any opposition from those who wouldn't take part. Some people, especially if they're going to spend 3 or 4 days a week, 6 hours at a time, might like to be a little more personal, but displaying their "guts" out for anyone to see at any given time, without someone putting in the extra effort of clicking a small symbol or something beneath a header/image. It's not flawless, but I think it would help streamer confidence which is good for Twitch, but also those who decide to spend their time with Twitch.
