I'm still a little baffled as to the purpose of a specialized file browser that doesn't integrate into a patch. Drag and Drop is not an option, as window switching on a Windows system creates a freeze in Jitter. Drag and Drop is also a tedious and sloppy method of choosing content. Instead of being able to use the file browser by keyboard or other methods, one must mouse the selection over to a particular drop point. What piece of software only functions using drag and drop as an input method? This is certainly not a viable way of performing. There is no functional difference between the C74 file browser and just using a system file browser to do the same thing.
There are ways of creating your own file browser with menus, lcd, and other convoluted methods. All of these efforts to reinvent the wheel could be eliminated if the browser was able to be integrated into a patch.
