About Cosmonautics: Deep Air
This mod simply adds localized air and gravity to cosmonautics using deep seas systems, this is just a temporary solution until air is added to cosmonautics standalone.
There is 1 major caveat to gravity, and that is atleast 1 room in your ship will need air due to deep sea memory cleanup.
