People have created a lot of maps lately but no parts. Many mods have been outdated, forgotten and removed such as the Engine Pack, Free Spin, Outer Space, etc.

Is it more difficult to make maps than simple pieces for your ship?
Will I be able to do these mods one day?

The ideas I have in mind =
-Pack of sports car wheels and engines with custom sounds.
-Wings similar to real life replacing the wing panels.
(I know a mod was created recently but it is hard to use and impractical)
-Assign any key on your keyboard with a part
-Engines of the First and Second World War.
