Last night I was working on the quest log, here is how it now currently works.. Quests you've accepted will appear in the list when 'Started' is clicked and the same method is used for viewing completed quests. For every quest you complete you get a QCP (Quest completion point).. It is shown as '[your quest completion points] out of [number of quests]' on the panel. Quest completion points could be used for both requirements and milestones. If a quest is selected on the list and then 'Info' is clicked. Your will receive information regarding the quest, depending what part of the quest your on, as seen in the second picture. As always, all feedback is welcome.
Oh I love having a lot of quests available, I really like you display it's description on the main screen instead of having to look for it elsewhere.
