The new chat system has some great features but it also removes frequently used stuff.
- Shift + Enter isn't opening faction chat anymore, it used to auto do /f and any message would end up in there. Bring back /f and make it work from every channel
- Same about /pm "name of player" "message". Perhaps it can auto open a PM window with that person after sending that message (same for faction, could be an option you enabled in the options menu)
