-If cancel is clicked during a download, don't just delete half of the the
downloaded files. It is very annoying to start updating, discover you set one
tiny option wrong, and then have to redownload the entire site once you've
clicked cancel.
-Update the help files.
-Fix the bug that, for some reason, seems to make random images not get
downloaded.
-Make the UI more intuitive; I've tried telling httrack not to crawl any
domains except the initial one, but I'm not able to get it to work.
