Improved version of this mod, now it saves the message you were typing before pressing up, in case you change your mind.
Functions exactly the same to how Minecraft's chat does for example.

Most likely has compatibility issues with the custom chat from WolfHUD/VanillaHUD+ and it's standalone version, will take a look at it soon™.

Fixed, original mod had some unnecessary code.

Now that issues have been fixed recommend using this mod with, VanillaHUD Plus (WolfHUD Continued) or Custom Chat Standalone.
