yeah a tool which you can select library files and move or delete them along with all of the supporting files would be extremely useful. I too would add my vote to a two pane PFE, yes I can open up two versions but its much more conveniant to have two panes side by side in the same window as I dont have to move and adjust the two copies each time I open the software, and I use a two pane view so much that I tend to use cr2 builder more than your excellent product even though I like your features a lot more.
