@octothorpe I tried it again earlier this year and ended up giving up on it AGAIN after a few months of trying to tough it out. The reason for my ultimate decision was that OS integration will never be as tight as needed, but also that PF comes with its own separate set of issues, and customer support appears to be non-existent these days, which means that these issues might never get solved. We already have that same situation with the Finder, thanks very much.
YMMV, of course.
