It seems like chat channels in Fopnu does not show only real user chat messages (as i see it in DarkMX), but a lot of status messages (users, joined, left, reconnections, username changes).

Some of these are important but only in some cases. Like you do not need to know when each of the members disconnect (maybe only your friends or someone you have recently talked to in chat), also you do not need to know connection interruptions in main chat (maybe rather in some kind of log which you would open on-demand).

Maybe there can be some toggle which would show these status messages while hiding these by default, because it is hard to find real chat messages currently and it wastes time.

In the Channels window go to the chat tab at the bottom and to the right of where you type to chat in the room, there is a button with 2 gears on it, press it. You can turn off/on the join/leave messages.
