When starting up PM should be able to resume the state from when it was exited.
It should be able to open (reopen) all of the open contact sheets--not just the last contact sheet.
If there were file transfers in progress it would be very nice if these were also resumed--or if it asked if you'd like to resume these xfers.
But come on reopening all contact sheets--Firefox and Chrome are able to resume sessions--this isn't too much to ask; is it?
