I think it's simple for HTTrack to support other protocols, even much simpler
than http/https etc, because it needs to do nothing but leaving those links
original. Many popular web copiers support that. 'D better user able to
customize the protocols.

I don't want to download all the links, but just the links with some anchors.
For example, if a page have a link /example/a1b2c3 but no
/example/a1b2c3#subtitle, then I give up the link; however if a page have both
/example/x1y2z3 and /example/x1y2z3#subtitle, then I need to download the
link. 
Currently HTTrack cannot differentiate anchors. Now I filter all with
-*/example/*, having to lose some important pages.
