Absolutely needed feature: in addition to "tell player" option in context menu we need "send mail" option. When you send a letter to someone, you have to write their name each and every time. Selecting them from the "social" list would simplify the task greatly.
"Send mail" to a selected player
Why? I mean, there's no major downside, but cluttering up that menu is still bad; it doesn't make sense to add a dozen commands that no one uses.
Sending mail allows you to specify a text message and/or send an attachment. If you are able to click on the player, then you can do both of those things (without paying the mail fee) using "tell" and/or "trade". It's not completely inconceivable that someone would prefer to send mail for aesthetic reasons or something, but I think that's clearly outside normal use.
I could see adding it to the context menu for offline players in your friend list (if it's not already there, never actually checked).
For Some GM's or people that is constantly composing letters..
This will be helpful.
I need this
This would still have great utility for the offline list.
i don't use the mail option, um, ever. but still a good idea
