ProvisionPoint maintains a single Site Directory which gives a clear and simple interface in which users can find sites. It provides the structure which is lacking in Office 365, with the added benefit of being to see a history of actions for a site via the Timeline. By default this Site Directory is open but you can trim what is shown by a hierarchy of users.
We have also taken this one step further by allowing the pushing of all the provisioning information, including all custom request fields, into a SharePoint List. This information could be displayed in web parts or used to trigger workflow when a new SharePoint Site is created.
