inbox folders/inbox sorting

as i am an artist on wolvden, i take commissions! due to this, i have quite a lot of messages coming in and out of my inbox. i believe that being able to sort your inbox via folders would be extremely beneficial.

alongside that, some sort of auto-delete field that allows you to input a phrase that it would check the title for. if the title says, for example, "puppies born!" and you asked the server to automatically delete it for you, every new puppies born message will be automatically deleted.

and, finally, auto-sorting field. for example, i would put "daily rollover summary", "puppies born!", and "trade bought out" into a separate folder titled "game notifications" and have the game automatically sort all messages titled that into that field.

i hope everyone can see the usefulness in this! i've seen other web-based games do this and it was incredibly useful when i still played them.
