allow users to view old Twitch account names after a name change
If a broadcaster does not stream often or regularly, it can be tough to keep up with their channel. If they switch their Twitch username and you don't recognise it on your follower list, there should be a way to view their past user names to clarify who the streamer is. Quick and easy, Steam has a similar feature that has helped me not remove friends after a username switch.
Have the ability to see an accounts previous name on twitch eg. https://pbs.twimg.com/media/C9xnOcZVwAAx5Xm.jpg and too adding the feature to pay a certain amount for an early name change instead of waiting the 60 days to be able to change it.
