FLAT SAILS!
To me the secret of low wind sailing is a good set of lightweight "Gentry Tufts" for perfect sail shape. Second in importance is "making you own wind' by sailing on an angle that maximizes boat speed; hence optimizing the air flow over the sails (apparent wind). Its in light wind that the streamflow across a sail separates too easily. As long as the "gentry tufts" - essentiallly tell tales all along the luff leach and foot are flying you have a decent shape enough to sail with. Heeling the boat to leeward will help with sail shape .... as well as a clean bottom will help top keep the speed up. With such tufts one can see the separations/stagnations .... and usually indicates in light going the sail needs to be as flat as possible - the tufts will immediately telly you if stagnated or separated flow. Increasing the flow over the sails by bearing off to keep boatspeed up is very important.... never dead downwind (in ANY condition) - better to tack downwind than to 'run' (run-an oxymoron if there ever was one).
