OT: Just in case webdevs reads this: you might want to markup clickable things as clickable (<a>). If you need a datapoint: I'm using Vimium for Chrome.
Also, I think there should be an option to show all of the websites. I don't want to keep clicking to see which websites I use, I just want to browse by scrolling.
Hmmm, what are you seeing that's not clickable? I don't use vimium and I can click on the site name, docs links, and tell-them-to-two-factor-via-twitter.
Whoop. Looks like the tiling system is relying on JavaScript instead of <a> tags for links:
An anchor would be good here if the clicking the icons also triggered a URL change, but as it stands a button would be semantically most appropriate
