Hello there!
If I had to guess I’d say I’m not the only person who managed to accidentally delete one of his chat tabs at random times when trying to switch really fast between them. That little “x” is just so close to the channels name and there also isn’t a confirmation request when deleting one of your tabs. I therefore suggest a simple “Lock Chat Settings” button in the chat menu. I don’t know how hard it would be to implement something like but it would be a great help. It’s also some kind of standard in other games I played.
Tell me what you are thinking about that. Sorry if this was already suggested.
