I'm not sure if everyone feels the same as I do, but I think command seats should be treated as regular command modules. I use command seats regularly when I need a light weight control system for a boat or a small vessal and its a real pain having to EVA a kerbal to board a command seat if its the only control system on the vessal. There is already a mod that treats command seats as regular command modules called "take command", but it only supports v1.1 as far as I know.
