I loved it, it has exactly what is wanted and doesn't add extra content that I wouldn't use in my case.
The only exception is that after configuring it with DiscordSRV it no longer allows you to send messages to any of the channels and you don't see the formal chat format either. By the way, I only have DiscordSRV and this plugin.

With this plugin I can create easy channels for players to chat. Developer helped me with a modified feature!

Is there any plan to support the speech bubble function above the player's head?

Developer is extremely dedicated to helping the users :) asked for some specific features and they were added within the day!

I asked for PAPI integration. Some hours later there was an update with request fullfiled!
