Feedback:User/Musha/Completed Quests in Quest Log

Can we please get an extra quest log in the quest window for quests we have completed? The quest window could have multiple tabs in it, one for active quests, one for completed quests, and maybe another that shows quests which have not yet been obtained. The Completed Quests tab could even have sub tabs which divide the quests by campaign. This would be incredibly helpful for us HardCore quest doers. :)
