In the HUD the same element that contains your quests (Labeled Duty List in HuD interface) is the same element that contains the Timer and Points distribution for Frontlines.

There's no way to make quests not show up in the Duty list so when in Frontlines the entire box becomes very tall and bleeds into other elements in my HUD. I would love to be able to toggle the quests off so I don't have to look at them when not actively doing them.
