A few days ago I built a glider in KSP. Pretty awesome at fist, but it got boring after 3 flights or so because there was no way of staying in the air without descending. So I started thinking: "What if weather, wind, turbulences and thermics was added into the game?" This is basically what this suggestion is. Weather, wind and thermics. This would give gliders a sence and make the game more chalenging, for example when you want to land on Duna or Eve, but there's a storm underneath you or if you want to launch a rocket. Would you like to see a feature like this in the game? (And yes, I know that there is a mod that adds wind, but it's pretty Basic.)
