I am not sure whether this is a feature that is under development or one that I have overlooked.
Using Favorites, I can have a quick link to Folders that I want to visit, but apparently not to specific files. This means that, if I want a collection of favorite images, I have to move them out of their proper directory or copy them to some kind of Favorites directory, either of which has problems. My recollection from using Bridge (which I stopped using years ago when I started using PM...) is that I could drag files to a Favorites type location, but that would not copy or move the file, it would only store its location.
In skimming the threads on this forum, it seems as though the developers have plans to add this sort of function to PM. Has that been done yet? If so, what is it called? If not, is that feature under development?
