To repeat what others have said:
Mesh Skins: get to camp and partially set up your tarp - allowing for a great view until it rains - then allowing the tarp set-up to be finished quickly.
Also - mesh skins seem to allow my tarp to dry some while stored in the stuff all outside of my pack. A stuff sack would hold the moisture in the tarp until you had a dry moment to shake it out.
