As a Roblox developer, it is currently too hard to obtain analytical data on your fanbase through the means of groups.
It would be really interesting to have a page similar to the developer stats pages offered for games. It could provide an analysis of the group member count through time, maybe even country and age statistics.
This would be able to improve games produced by said groups tailoring certain things to their popular audiences. It can also provide simply interesting and useful statistics to show and use as developers (member count and stats isn’t all what this can be used for. Purchases, rank changes, and more can also be done).
With more data on your fanbase, it can be made easier to develop certain things as you can set priorities based on data such as patterns given by this menu.
