When I'm on a low orbit I prefer FREE camera mode, cause body I'm "falling to" has to be "below" :D
However KSP keeps switching camera mode to AUTO every time something happens: switched to far away vessel, ended docking etc.
So here is Keep It Straight - mod that saves camera mode between scene changes and restores it.
