check to not send formspecs to death players :/ (done?)
priv checks (bailiff / staff) before sending out a formspec to the target (done?)
do I have to fs-escape chat messages?

create formspecs how to replant / how to chat (done, with strange issue on quit-event)
add a licence
colorize answers / maybe even play a notification sound to provent the message getting lost in the chat flow
translation
test with a (target) client having formspec_version 1 (older than 10/2019) (I expect every sender to not have a super outdated client)
