[Feature Request] Possibility to change the visible name of a chatter

halefa via Discord:

When watching a live Twitch stream in the browser, you have the option to click on a username and change the name. This does not change the "real" name of the user, but what is shown to just you. (I think it is also only in that specific chat ....?)

It would be cool if one could do the same in Firebots dashboard. This can be helpful if one wants to add additional info to users like help with pronounciation.

I know you can save metadata for users, but I am looking for something that automatically always is visible and does not need to be opened by clicking on the user.
