I think I mentioned this several months ago. But when I make
a project with several websites in it, frequently I want to
add a new site to a project, but not try to crawl an
existing site. So I would like a way to comment out the
existing site, and only add the new sites to my project. 

We could enter one site per line in the website list, and
prefix a site with '#' for a comment, or something similar. 

I hope this will be considered in a future release.
