Crew R&R
This mod is focused around the idea of encouraging the player to keep a deeper roster of crew, and to increase the value of individual experienced crew.
This mod gives crew members a 'cool-down' when they return to Kerbin, so that you need to use a more varied crew rather than just Bill, Bob, and Jeb. It also changes which crew are automatically selected, so that the most-experienced crew who has least-recently been on a mission is picked first.
