I suspect most of these are in the works already, but I thought it was worth putting up a thread to make sure.

We currently have a list of names, their locations ("Not Logged In" is displayed if the character is--you guessed it--not logged in), and the option to remove a selected buddy or send them a message/note from the PDA.

It'd be awesome if we had these additional columns in the interface:
» "Last Online" -- displays the last time the character was ingame. Basically, the output of /buddy last "name".
» "Note" -- displays the last note you sent to this buddy, or blank if no note has been sent or the last one was read already. Perhaps this field could be like a textbox, and the player could edit their buddy note from there.
» "Location Notify" -- toggleable checkbox for keeping this person's PDA updated with where you are.

I suspect some of these are already being worked on. Any other features people can think of?

duel accept
group create

while we're at it? please? We now have half a GUI to handle these, but at least one player still needs to use the command line interface with these interactive commands in order to make them work.

Yeah, I've lost buddies due to them not wanting me to know where they are.

If there was something like a "permissions list" for buddies, that would be neato. As in, I could allow Dr. Lecter to see where I was if I wanted, but he could choose to block that aspect from HIS buddy list transponder.

I second Leber's post. It'd be cool if I could block my location to certain buddies. I'd like to know when my favorite arch-enemies are online, but still be able to surprise them... and, I'm sure, vice versa.
