A global schedule to gather all upcoming events from big streams
Like you probably have noticed, popular streamers and streaming organisations provide their viewers with a weekly schedule on their profile page which covers almost every need. Except for rare events, like tournaments, 24-hour marathons, or big charity-funding events (like AGDQ). What I would like to see is a way for those streams to submit those big dates to something of a "Twitch programme schedule", which gathers the information and makes it easy for the daily viewer to see if there is anything special happening within the upcoming days, and if so, what time they start.
A global programme schedule for every featured streamer to put important times and dates in would help the viewers prepare for upcoming matches and events, and most importantly, they will know where and when to tune in.
An example could be a schedule made out of the top channels of all time (Riot Games, Blizzard, ESL_Csgo, Dota2ti, etc), where each individual stream post their official schedule. Each individual viewer would then have the opportunity to filter out channels that he/she is not interested in, making the list more personal and relevant.
