Security: End-all-active-sessions & timeline-logs of config changes

At the moment, you're not in control of your logins on my.nextdns.io which is detrimental to your account security.

When you forgot to logoff somewhere you can't even recognise this anywhere nor end the session from another device.

Ideas

• Login-Security
• Show the time/date/browser/device & IP when the last session on my.nextdns.io took place
• Dashboard to show all active logins and to terminate these
• Function to end all other logins "1-click-button"
• Forgot-To-Logoff-Prevention
• Function to logoff automatically after a period of inactivity e.g. 5min...3days
• Notification by mail when I or someone else logged into my account.
• Configuration-Security
• Track changes in configuration in a timeline and optional mail notifications, so that I can undo these or to facilitate tracing configuration related errors in websites.

Something like this:
