This plugin makes it that chat bubbles appear ontop of players head instead of only in the chat bar. Other plugins like this doesn't make the chat bubble follow the player but this one is improved and for 1.14.x.
Description: Chat Bubbles is meant to be a free plugin that allows players' messages to appear above their head and servers to customize the way in which this works.
