Paracutes in SimplePlanes are a bit lackluster, an idea to improve them is the ability to repackage them, say, the activator group was enabled and the paracute would deploy, activation group disabled, and the chute would repackage, similar in function to how in SimpleRockets2. Another thing would be apon coming to a stop, the paracutes would fold into a half deployed state, they would also do this at high altitudes when the atmosphere isn't thick enough.
