^ Yeah VP, you appear to be correct. The startup options only seem to apply to a library that you already had loaded. So they work when you stop and the restart MC.
I don't change libraries much. There's almost no need to do so with MC unless you have vastly different collections of some sort that you are trying to manage in totally separate ways.
For the OP, unless you have a very well thought out reason for doing so, you might not be doing yourself any favors using more than one library.
The Load/Save views technique still works of course, and it brings back tabs, splits, etc, but it obviously requires you to select that from the menu structure so...
