[Sugar-devel] [DESIGN] Browse PDF handling

[Samuel Greenfeld]

Something to watch out for is that many websites already like to open a
separate tab or window for PDF documents, sometimes via Javascript and
sometimes by setting the target frame/window.

Sometimes these sites directly link the PDF file; other times they attempt
to include it inline.

If we intend to support tabbed browsing, these behaviors could result in an
"unused" tab being opened besides the one showing the document.
