aaahhh ofcourse, last night I wasn't very sharp sorry.
All those things are possible, I'm going to think about the easiest way to implement this.
My key issue is that I want to keep it intuitive. I have seen so many logbooks that just aren't made for my logic I guess.
The next couple of days I'm going to be away, but expect something in a week or so.
Thanks a lot for the input; as I'm still flying the small stuff it's good to hear the big-guys perspective.
