I believe that it would be a substantial improvement to the AOPA flight planner and everyones situational awareness if TFRs were depicted on the planner even when they aren't currently active. I don't mean to mention the competition, but it's the easiest way to explain what I think is a great way of showing current and upcoming TFRs. Take a look at SkyVector, and how they display them. Soon to be active TFRs are depicted as a orange ring with clear and concise info on time remaining till active and active TFRs are red. They show up on any visible part of the VFR sectional, whether you have a route planned or not.
