It would be amazing to have chat bubbles
regional chats are wothless because in a pvp situation you dont have time to look in your chat.
imagine if you attack some random guy and try to kill him because he gathering your resource / whatever and 5 after you killd the poor bastard and lootet him you see in the puplic chat if there wil be a puplic chat ) < hey im sorry dont kill me i give all stuff back didnt know thats yours > etc etc
so maybe if you know what he told you if you fight him you didnt kill him .
i missed that feature extreme in DF and killed many times ( and get killed ) someome.
and its nice for the roleplayers
btw my english is not the best
