Thank you
@Viktor Jaep, good to your word, as always; and thanks to
@rung for testing too, great stuff.
I don't use screen so wasn't 100% sure what to stop exactly, so I stopped the TS service and ran through the steps above.
Any odd messages that you see may be as a result of that; but feedback all the same, in case of others doing these out-of-whack installs

.
I did not initially see item 7 in the menu above but probably not on the "latest latest" beta; restarting it gave me the menu (v1.1.1).
Minor comment for Custom item 7:
- I would suggest that rather than just state a time there (01:00 in grey), that if it is DISABLED (being the default), that you just print (state) "Disabled".
- It was not immediately apparent (albeit not green) that 01:00 in grey meant disabled, until you enter the menu.
I received a "FAILURE: Tailscale Service Restarted" email; not 100% sure if that was due to me stopping the service (rather than screen).
Again, thank you Viktor, this is awesome.
