I am a developer who wants to make more Extensions, but currently struggling for ideas. I personally prefer to create Extensions that utilize information already in the Twitch API and display it in a useful way. I currently have two Extensions already in this vein:
Latest Follows - gets the authenticated streamer’s followers as they arrive.
Event Countdown - displays a countdown to the streamer’s next scheduled event.
I am currently working on a third Extension which will use the streamer’s Team data to give info about their Team mates.
If there’s any streamers out there who are looking for Extension and think I could be of service then please do reach out. Similarly, if there’s any other developers who like my work and think they can improve it - or think that I can improve theirs - please let me know!
