Enable slideshows from every category
Please enable full-screen slideshows from any category or subcategory: movements, schools, genres, nationalities, centuries, etc. Although researching particular artists is interesting, another fabulous use of such a collection of images is to view randomly-ordered (with an option/preference for chronological) sequences of full-screen images. An icon for displaying an overlay with minimal identifying info (without disrupting the slideshow) would be great. My preference is for manual control of moving to the next slide, but an option for automatic transition (at a chosen interval) would be great.
