This is interesting.. I like it in that its a "Leave" ... but part of me would like this choice of default behind an option. As with the previous changes in this area I'm uncomfortable about us changing how it behaves, but would like the extra capability to choose..  I'm going to say Approve, but I'm interested in your opinion about if we SHOULD have an option or not?
