It would be nice to change up the gui a bit. Modernize it a little.
Like adding easier friends request.
Setting up a section to allow for metnoring.
Adding features that are command based into the gui somewhere.
It would make the game less confusing to some of the newer players.

Don't take away my commands. I like them. But I think it would be good to update the gui so it doesn't feel so dated.

Any thoughts?

For Example setting permissions for guild, making it easy to join/leave guild.

Have you considered throwing together some graphical mock-ups of how it might be made more intuitive?

When people complain about the look of the PDA, I always suggest people draw up some concept drawings. I've often said I'd do an ingame mockup of a new PDA if people would provide concept drawings that receive enough love from the community.

I won't do just anything that people throw out though, especially not currently with my time being spent more on my MDI HUD project.
