I have seen many ideas for the Carrack modules , but wouldn't it be great if you a single size , double or triple sized ?
for example the medical bay
size 1 very basic treatment for three
Size 2 advanced medical treatment for one within compartment and a canopy/tent extends from one side of the module for basic treatment of another three
size size 3 main module can apply advanced treatment to 3 but two sides open for basic treatment of another three each side

as you can see this would give obvious benefits for increased specializing of the ship and I am pretty sure that you could apply the same logic to many different modules

as always i would like any feedback good or bad
