would be superb if you could sort the mission list tree with or without the user doing it.

Aye, this has been asked for before....

What would be your sorting criteria?

Sort criteria? See 1.8.8 for that info. It uses the standard sorting algorithm. if the names are equal, i.e. 'escort' then sort by details.

What sort method are you using, blacknet? qsort? bubble? merge? :P
