In the settings it would be great to have a sort of a "Admin dashboard" / overview where you can quickly see some health info regarding your cloud. Like the following:

Admin dashboard

• Are there any sync problems
• Does someone use outdated clients
• Where is the quota full
• Is there anyone not syncing since a long time

Further ideas:

• Does everyone have 2FA?
• Does everyone have secure passwords?
• LDAP server connection
• Overview who accesses Nextcloud from where (Device, location)
• Show all outgoing share links
• Who accesses share links from where
• What are guest users doing?

We have to watch out to not go into the field of too much tracking though.
