Hi guys. What about fans that already has a trajectory? Like 4 new fans - Up, Down, Left, Right. Pre-made. I'm sorry, but sometimes it's really boring to set EVERY fan trajectory yourself. Like if you doing pipe that should transport elements, and it should has a huge fan system inside to work. It would be very nice and USEFUL things to save your time on creations with big amount of fans.
With the current structure, you can set it exactly how you want, power and direction. I don't see how it would be tiring to set each one unless you had like 50 fans. Then I might suggest using white hole and a wall to block off sides you don't need.
