Hey! Sorry just getting to this now.
We're currently working on a page that will let you do similarly to what you described, but it's not finished yet. Though it's not currently available to the public, here's a direct link where you can check it out: Panjo Popular Tags.
On this page, you'll see the most popular tags that members are following on Panjo. What you're requesting is a section of the page that shows you the # of listings within each of those tags. I've forwarded your great feedback to the team as we continue working on this page.
If you have additional feedback on other features you'd like on this page, let us know. Thanks again for sharing your great feedback with us!
