I think the idea of changing the chat interface is a good one!
I am also waiting for the change of the "TAB - scoreboard" interface.
I would like the commands and all content of the scoreboard to be translated into other languages, e.g. Polish, just like the new launcher. It is not a time-consuming job. This function is very useful, there are very young players, as well as older ones without knowledge of foreign languages, and the speed of learning commands in your own language will be a big + for the community.
