Yes, it would be useful to me. Sometimes old ports comes with new 
default options and brings new dependencies which I do not want to have 
installed with update / upgrade of port, but it is not easy to track 
these changes. If portmaster will have option to firstly show above info 
about dependencies and wait for confirmation, I will use this feature. 
Maybe in combination with some advanced logic: if all dependencies are 
installed, continue without confirmation, if some dependency is missing, 
wait for my confirmation.
What you think about it?
