Sorry that the website is not more intuitive. This kind of feedback is needed to help us improve it.
We’ve tried to design the website to support many devices and browsers, which is a challenge, and it sounds like this is a case we haven’t handled correctly. We will work on fixing that. In the meantime, try to click and drag the lists to scroll them.
Regarding tutorials, we’re working on a help system for our tools since the they’re becoming more sophisticated. We hope to have it online soon.
If you could provide a little information, what device, operating system, and browser are using to access the website?
