It makes the chat look better in various ways, see the preview (opinion not guaranteed)
The chat box hides soon after a message arrives...
...but it shows the context again once you get a new chat or start writing one yourself.
It has the Rolling Chat script built-in
Links inside messages are clickable
It hides/shortens the most annoying system messages ('Since there aren't many players...')
Indicates what kind of message you are typing (all, team, group, as mod)
You can configure position/size/timings and disable functions on the TagPro Homepage (look for the RL CHAT button on the homepage and on the scoreboard)
Better settings Better looks, edit the options on the homepage and on from the scoreboard in-game (it uses tpul)
Scroll up to view all previous messages. (needs to be enabled in the settings)
Position the box outside of the game viewport, in the corner of your screen
Sounds: Bweb when you receive a message, Dink when someone joins and Donk when someone leaves. (yes, the Volume Slider® works on them)
Works with Firefox (pls make all browsers finally use the same standards)
