1) Make it possible to choose the day which starts the week
2) Make it possible to choose 24h time or 12 AM/PM time
3) Make it possible to add a description of the stream (name of the game/creative, etc)
4) Make it possible to edit/remove the text "Countdown to NAME upcoming Twitch stream"
5) Add a text which says "Next stream: NAME OF THE GAME", make it possible to hide or show would be great too
As a variety streamer, these options are very valuable for my stream and my viewers. This way they know exactly which stream is coming next, creative or game and which game is played.
