I remember the old place page having this feature-- it was great (even though you could only see the amount of sales if you didn’t own the place). This is totally something I would love to see happen soon- since it looks like paid access games are making a come back in the community.
Knowing how many place sales you’ve gotten is only possible by doing it manually, and when you have a ton of sales each day, this gets really really annoying really fast.
Now, I would make myself an extension for this kind of thing- but the ROBLOX-supplied product-info API does not provide the amount of sales that a place has.
