I think there should be a new map system that shows discovered runways and where you are going sort of like in real life. You could also add a autopilot, and please add a mapping system that allows you to plot different points to turn. You can also add a career mode which allows you to fly routes and complete missions such as military transport to earn money. Then with the money you can unlock parts and buy a bigger work space. Sandbox mode would be the same as it is now but with access to the map and autopilot system. Also add a "shield" piece that can cover the fuselage parts, which sort of smooths out the hull, and would be one giant piece.It would be like shrink wrapping your plane, and then you could delete the fuselage parts below it. You can also make the physics and terrain more realistic in this update(s). To tie in with this you can add flaps and flexible wings(and maybe a vector-like system to round wings?). Another thing I want is a vector system to add paint jobs to your aircraft. If you don't know what I mean by vector you can look up Inkscape and look at a few videos of how the dragging around and stuff works with that. This whole entire suggestion could be added in multiple updates too, as not to keep us waiting. I know this may be hard since you are also working on Simplerockets 2 but Simpleplanes is still growing and adding these features could help keep and add people playing the game. If it wasn't for Youtube I probably would have seen Simpleplanes' graphics and restrictions and just give up on it right away. This update would especially help bring in those who know more about planes, while keeping the game pretty simple. If you would like, you can add a simulation mode that adds in the more complicated map, flaps and more realistic flight physics. I really like your games, and it may be hard to update the game right now, but I think these updates would really give the game a surge of new players and old players coming back. P.S. I have an account, Simpleplanes, and Simplerockets 2, both games which payed for myself.
