Currently, the Marketplace Add-ons interface when opened within Designer only contains the more significant, Alteryx made tools:

Which is a very useful feature, however if the tool I want to download is not on this limited list (or, I want a particular version), I still need to go through the Marketplace to download this.
It would be great if this functionality had all tools on the Marketplace included - potentially with the option to filter to Alteryx made tools only.
Cheers!
