We needed a solution to manage a basic list of about 20 PDFs on a page that update monthly. Uploading and hand-linking each file through the WP media manager worked but was slow. With the BannerSky plugin we can put up a month at a time in just a few minutes and never have to touch the page itself; it just pulls categories in through a shortcode. It also keeps the PDFs all in the same place, instead of having to look for them scattered throughout the WP Media Library. We don't even do much with it, but this simple plugin has still has saved us a lot of time.
