A diff of versions of the design doc turned up some minor mods:

* drop "Transfer Vertices" checkbox
* align controls in layout of Precedence Tab
* new layout in AutoMatch Tab
* after New Session, display session name in titlebar (currently it only =
works for Open Session and Save Session)
* auto-number default session name (e.g. Session1. Currently it is just =
"Session")

Let me know if you want me to hold off on any of the above (half day for =
everything).
