More advanced comments&reviews system in O365 Store
Currently Office365 Store allows anonymous comments on the product site, which could destroy opinion about each app by haters, trolls and competitors. It makes O365 Store unreliable platform for selling software. Each comment should have mandatory first name, last name, organization name, when app as used etc. You can check Capterra (capterra.com) or GetApp (getapp.com) to see how the comment system should look like.
