Give an option to show previous username when you change it!
I have wanted to change my twitch username multiple times, but I have decided against it because I do not want to have to go through the process of reintroducing myself to everyone that I have met previously in chats and talk them through me changing username. I am a moderator in multiple channels, and it would create a cluster if I completely changed my username. I think there should be an option when you change your username to TEMPORARILY put your old username in parenthesis next to your new username to avoid this issue. (An example of what I mean, New Username (old username): Hey guys hows everyone doing today!) I have talked about this idea in multiple chats and it seems to be well received. Many people that I have talked to have expressed the same feelings when it comes to changing their username, and I think being able to temporarily have your old username attached to your new username could relieve a lot of those problems!
we need to be able to view the past username of the current username of people in chat. this would be good for us to view so we don't make the mistake of someone banned to get unbanned because they changed their username. old school runescape does this when people change their names it keeps it until for a month when names are recycled. there is people that make alts or change their username to get away with things and go to other chats and be toxic .
