recognise PDF frames in snapshots
I couldn't find if it has been already discussed but I noticed a pretty annoying problem. Many Paper distributors show their PDF full texts in a separate frame beside a html bar and when you take a snapshot you don’t get a pdf file which you could easily rename and open but you get an html file and you have to search for the pdf file in-between al these html supplement files and rename it manually, or you have to save it and drag and drop it. This is pretty annoying.
At least with Wiley Interscience there is an option in the right hand frame called something like "display pdf in a separate window" - this removes the frames and allows proper pdf saving. I don't know whether there is something similar for other distributors.
