I'm having a problem with filter ranges myself.

I downloaded an entire thread of a forum using the following filter:

-*
+*xyz.com/showthread.php?t=123456&page=*[0-9]

and I used the first page of the thread as the starting page as follows:

<http://xyz.com/showthread.php?t=123456&page=1>

This worked perfectly and downloaded 559 pages of the thread but after
sometime passed I wanted to download only the newly created pages in the
thread so I tried to use the following filter:

-*
+*xyz.com/showthread.php?t=123456&page=*[560-563]

But this did not work at all I suppose because HTTrack still does not use
normal regular expression so I had to use this filter instead:

-*
+*xyz.com/showthread.php?t=123456&page=*[561,562,563]

and I used page 560 of the thread as the starting page as follows:

<http://xyz.com/showthread.php?t=123456&page=560>

No suppose I needed to only download pages 560 to 1000 then it would take me
ages to write the filter for that as I would have to include the number of
each page from 560 to 1000 in the filter.

So does the developer of this software intend to ever include the ability to
use standard regular expression within the scan filters? If this in inclued
then this software would be the best website downloader in the world.
