Parachutes are extremely fundamental in capsule landings and even in planes.
You could select the type of canopy (round canopy, squared canopy or square rounded canopy)
Also adjust the size of the central hole that would increase or decrease drag, with this drogue chutes would be possible.
One last thing but an important one, is adjust the angle of deployment, with this multiple chutes wouldn't touch each other.
This could be a really good feature
