Simple suggestion: Make the ALT+D reply to a player's "DIRECT" the permanent chat mode.

Let me explain: Right now after replying to a DIRECT with ALT+D and hitting enter the chat mode changes back to "LOCAL". This is not optimal since you have to use ALT+D every time you want to reply.

If, for example, you receive another DIRECT it's getting really messy and ALT+D is not really useful anymore.

For me the greatest thing about ALT+D is that I do not have to type the name of the guy I am responding too ("Haxx0rz 175 Soulfl1 Chegger") and that I am able to answer much faster. So I'd really want it to be more be useful.
