I tell you what I'd like to see:
Guild Flag.
I know Super Sokre just went to all the effort of getting a few guilds to upload flags, figure out a standard template, etcetera...but that's a finite solution to an infinite problem.
Each guild could have a spot to upload their guild flag. I guess it shows up right next to the guild name.
With all those spiffy new features, figure the client can read a single image off a defined website: If guildfort taken over, set flag image to
http://guilds.graal.com/#g.png;
Expand as necessary - a Modern Flag, an Ancient Flag, a Spraypaint Tag, a Monitor Image for spaceships maybe, whatever. So any-old playerworld can make use of the Ventrue insignia when they've taken over something of importance.
Make the global Graal environment a little bit more integrated.
