As a Roblox developer, as far as I know, it is currently impossible to freely drag + organize your gamepass order on your games page, and I would want to do this because we would be able to put our most commonly bought Gamepasses on the top row or the most “appealing” ones anyway and likely generate more sales rather than the players scrolling down to see all the gamepasses.
Personally as a developer, I really really want this feature. Being able to freely drag gamepasses into the order I want to and add new ones in where I want to would just be wonderful. Although it’s not a necessity, I would like to see this implemented at some point in time.
