Nice one; it works great!
I would prefer it if the tool linked to the existing common domains instead of only showing the available ones. For my search,.org .org and .com are not available, and I wanted to look into what they are about.
Thanks! I hadn't considered folks exploring existing results for curiosity's sake, but that's a good point. I'll show taken domains and add links in an update.
Links to all results (not just domains) would be nice, too.
