Is your feature request related to a problem? Please describe.
Adventure appears to be more established when it comes to dealing with chat messages. It has many features that this project can inherit from using it.
It abstracts Text components, boss-bars, sounds, and they even have an NBT API if you need (provided you also want to migrate from yours).
Describe the solution you'd like
Stop using craftlib-chat
and move to adventure
.
Although, I understand if you don't want to make the move into something made by another person/team.
Either way, thanks for the time and effort you put into this project!
