This change seems meaningless without additional ways to show off plugin functionality to potential buyers.
How is someone going to justify putting down money for a plugin if all they can see is some barebones asset description text (no markdown or anything, yes you can link to external domains but that’s a hack to begin with), no thumbnails apart from the main square asset thumbnail, no video/gif to show what the plugin does? We need markdown support, image/video/gif reels, and other features like reviews and statistics to promote our plugins to justify higher price points.
It would be nice if the order of improvements to the plugin marketplace would be additive, I don’t think this step as the first step is the best choice.
