A great feature that I think should be added would be 
the ability to limit httrack to sections of a website.

For example, I would like to backup 
<http://www.ticalc.org>, which is a HUGE site (in case 
they go down sometime, like adcritic.com did)
But, I already backed up <http://www.ticalc.org/pub/>, 
which in itself is 700 megs of the site

So, I would like to do something like type in the urls 
box

<http://www.ticalc.org>
-http://www.ticalc.org/pub/

That would only download all of ticalc.org except for 
the /pub area.

Please let me know if this is possible.  I LOVE your 
program!!
