Thanks, I took a brief look. My only concern with using thought icons in what will normally be accessed as a WebBrain is they currently only work when accessing from a desktop. I haven't found a way to enlarge them on an iOS device (I don't know about Android devices) and since that's the way I sometimes access them I've tried to concentrate more on the text in the notes. I'm guessing this will change soon with the release of the iOS and then Android applications.
Also, it takes a little longer to enlarge them, than read the notes when the thought is activated. On further reflection this seems like a decent tradeoff because you can only read notes when that thought is active, but you can enlarge the thought icon for any thought that's visible. Since you primarily use icons, I highly recommend you add a note to the help section to resize the plex so it's full size (drag the notes down). without doing that the thought icons may not be able to expand to the full size. The example of this is the "What infrastructure is within 27 inches of sea level rise in FL". Also, wow $66 billion. My other feedback is to make the link lines darker. I've included a screenshot that I think showcases this. I think it's a bit more specific for the SCC in the News section than the others because the text is dark blue. What a great source of information about this. Lots of great stuff. Thanks for sharing!
