The tool is good, although it still lacks some functionalities... but unfortunately the server is 200% slow.
Every time you click on any option in the interface, you have to wait (even up to minutes) for the information to appear on the screen.

I'm not talking about displaying Google results, but loading all the option pages of the site.

I think the server has run out of resources for the flow of traffic they are receiving and, if they don't improve this, the tool will not be worth it.
