Excuse me if this is already in 4.6, but one thing that has always irritated me is that the Save snapshot lightning bolt drop down list, in the IPTC Stationery Pad, for example, only allows typing of a snapshot name. It would be very helpful for the Save... choice to open up the finder's save dialog window and allow me to populate the snapshot filename with a currently existing one so I can overwrite it or modify it for a different version name. As it stands it's a bit tedious to make different versions and have to clean up filenames in the finder outside of PM.
