There is a program called Listary at
this linke. It has the ability to provide a search box inside Explorer windows and Save/Open dialog boxes. It would be nice if FARR can that kind of integration too.
So basically, when inside an Open/Save dialog box, you can call up a stripped down version of FARR so search for files and folders, which I guess should not be limited to what is indicated by what is set in Search Folders.
