I've clearly learned something by all your feedback. It used to have a more obvious name before that I couldn't use because of domain name real estate. I had to change to Crosstips but didn't pad it with more explanation of what it does. Plus having stared at it so much myself I got "home blind".

But most of the complaints say it needs to be more explicit because they didn't realize it was a crosswords tool, which inherently means they DID realize it was a crosswords tool.
