isnt there a typewriter font?
This would be really awesome. There are however problems I can see arising: when multiple people write at the same time, and how would the formatting work, like, will the "typing" text always be the last, first, or where would it be it's position? What if someone enters their sentence between the others?
A good formatting idea would be to have, basically, a separated chatbox displayed under the existing one, and the text would perhaps be smaller. Or have the currently appearing blue font above the chatbox, instead using lines and showing who's typing what.
Also there should be a check for commands, if anyone decides to do this. I don't want people to know when I am about to do something with commands, no matter what it is, even if it might be just /sit, it's going to be spamful if that would happen, even remotely. Also worth mentioning that teams should also be restricted to that, what if someone wants to say something in team-chat for TDM's etc? Even if though it would have more use in roleplay.
Perhaps a sweet feature along with this would be to have a special Blockhead pose while you are talking, so you can know someone's talking without looking at their player name (if it even appears) and then top-left corner.
There can be a lot of problems concerning this, including a lot of addressed situation that need to be taken care of (like I said about the teams, about multiple people talking at once, about chat mixing etc.).
