I'm embarassed to say that i don't really remember how to use Web Link Captor very much any more... DC member ewemoa may know how to use it better than me at this point.
It seemed like such a good idea for a program at the time, and coded in a combo of C++ and Python I thought would make it very extensible. Any options you can pass to google to restrict search you should be able to pass to the google-configured searches in Web Link Captor.. Let me know what you figure out..
Maybe someone will think of a program i can turn WLC into that would actually be more useful than what it was created to do..
This issue was actually raised by one of my friends and I thought it was a good idea. It would be awesome if there was a software that could limit searches to your bookmarks. It's almost something that the bookmark managers should include. I wonder if Linkman would be open to the possibility. But it would probably be more useful as a standalone tool that you can load in whatever list of domains you wanted.
