An Interesting Idea.... However to do this everyone would need to add DeepBot as a channel editor. A number of people have issues giving a program that level of access.
An alternative that I am working on is to be able to open the broadcaster dashboard within the bot. This would allow you to achieve this without giving special permissions to the bot.
As for stream notifications, I was recently made aware that OBS allows you to display text from text files.
So I can add a mod level 2 command to save a note which the streamer can enable.
Good suggestions, will keep you updated on how development pans out.
