New isn't always the Best
Don't try and fix something that is NOT BROKEN! Like seriously why do all companies/people like to do this when the current system is working like a charm.
I feel as though you're being forced into this new idea where the "tabs" are going to be your first glance--if not a trailer like YouTube--as the streamer you are to other streamers or viewers even though as of the current design your panels are doing the exact same job as the tabs will be doing soon.
Personally I like my panels the way they are and to customize them the way I want too. If there was a way--if we get enforced into this idea--to have instead of different tabs keep it current with the panels and just add everything to one page such as the schedule as a panel instead of a tab similarly to 3rd party schedule panels and maybe instead of really updating to tabs update panels to where you can have more extensions and overlays to the stream especially if you play multiple games like me as a variety stream and may switch half-way through the streams and instead of updating the extensions from Destiny to Borderlands it switches on its on since it's already there without having to update it again.
