I have users who want a list of all of the sub sites under a given web site that they manage. For example, we have "Consulting" sites under two site collections along with other Lines of Business. Under those two sites are an additional 125 sub sites between them. They also want to know who owns them since often they are created without their knowledge.
In SysKit Point version 12 released in February 2020 we added this feature on the Permissions Matrix report - now this report can show all subsites under the site collection together with permissions on these subsites.
