What a pity. I find the surrounding frame most interfering. And it makes hidng the site quickly when reading is interupted an embarassment.
Depending on your browser and operating system, there are probably easy "workarounds" for both of those issues.
For the first, zoom the page unti the border is almost gone.
To make anything disappear from your screen quickly, simply keep at least one "innocent" frame open. Rather than trying to close your library screen, simply click on that "innocent" frame. Your computer will quickly bring that "innocent" frame to the "front" and your llibrary frames will be hidden.
