As the original poster, I like the plug in, BUT, and that is big one, the lack of multiselect and gallery creation is a MAJOR drawback, to create a gallery one must go through unnecessary hoops to get it done, something that’s done in no time in the standard WP Add Media function. Worse though, when the standard Media function is opened, it now displays DOUBLE files, apparently from once looking at the whole, then for subfolders again. Some issue when the two talk to each other?
After creating subfolders and moving files around, which I thought was fantastic and intuitive, I wound up moving everything back due to the above MAJOR issues.
