I've always wanted to see two upgrades to /role and /anon:
- a way to go anon, but still display your guild tag (eg. /anonguild or something), so that /roleplay could actually mean "I'm roleplaying"
- a /dnd (/donotdisturb), so that Dial a porters who are "off the clock" can use it, ALS people who don't want buffs can use it, etc.
Highly doubt we'll ever get either, but Blue will have custom content, and new chat commands are probably easy to add, so I wouldn't rule it out for sure either.
