Info Boxes on Channel Under Stream

As a streamer, I may have additional information for my viewers such as events, giveaways, special goals, or goal or tip menu item descriptions. There is currently only 160 characters available on the entire channel to provide information to the viewers.

USE CASE EXAMPLES:
Some of my tip items are labelled as "wishlist" I would like to provide my viewers with additional information about these items. This information would include that when a viewer tips for one of these wishlist items, I will then go shopping for the item on stream so that the tipper can choose anything like color or style of the product.

Subs get a bunch of special bonuses like exclusive discord content, premium snapchat for a week for free, and can even join me in games while I'm streaming. I currently have this additional information displayed on my screen and would like to remove it and repurpose that visual real estate for something else.

I was watching AfterHoursGaming (Jaunty and IronRose) have an anniversary stream tomorrow and having an announcement a week ago would have been nice cause I spent all my PD TT__TT
