New v1.1 - This allows you to create a file with replacements on your chat messages. Want to filter obscenities out without having a server mod? Just add them in the clearchat.regex file found in the config directory. Do you want to add new filters but not reload? Just press the key to reload your file (Insert by default), and you now have the new rules in place.
With the press of a key you can now clear your chat without having to leave to the main menu. This is a client-side only mod. Licensed under the 3-clause BSD license.
