Whole Web site grabbing
For offline viewing on a tablet or pc while travelling: Enable WHOLE web site grabbing to a single PDF, including all the web site's subpages and with it's site local web links and menus converted as links pointing to the included subpages in the pdf document instead. Now, that would be an impressive feature. Single page conversion, NOT. All conversion sites and related programs does this.

You can grab all internal links with a maximum number of pages via some commands, and pipe it to curl as a set of parameters. I would be worried about pdf'ing a site like cnn, because its a lot of pages.
I'm not too sure what "Single page conversion, NOT. All conversion sites and related programs does this." means.
Could you clarify?
