In reply to Charlie Sasser.

There are only 30 or so block themes right now. In the future, there will be 1,000s, so a simple tag won't cut it for filtering. Kamal has not implemented his own filtering system yet either.

This custom directory has a lot of other features that would be useful for showing more about a theme, such as its full color palette and typography options, without installing it. You can also view many of the blocks in action. The proposal is about bringing these features over to the .ORG system.

As far as branding, I think he's stuck with the Gutenberg Hub name. He created the site at least a couple of years ago. :)
