as I remember there was an option "don't display completed quest" on the right side just the progress one.
Did u just remove that option or it is somewhere hidden I cant see?..
u referring to blizzard!
At the right panel where the quest display if u right clicked there was an option "hide completed quests" or something like that so only the quest in progress were displayed. At the moment there is no such option so I see all quest at the panel.
the changes made to the quest tracker in 6.0 seems to have removed some features. Such as hide completed, hide quests in other zones etc. The sorting by distance isn't reliable either.
