"Save to power off" Message on I2C-Display on end of shutdown
Whatever the last message on the I2C-Display was right before initiation of shutdon, will obvisously remain until shutdown has completed and gives no indication about shutdown status.
As SD-card image can possibly become damaged when power is cut off without proper shutdown, it would by great to have some indication about finshed shutdown procedure.

Good suggestion, will try to come up with a solution, but unfortunately one of the first thing get killed by OS during shutdown is nanodlp so we do not have access to any hardware to change status. And we could not be sure if everything goes well.
Maybe you could wired LCD power to RPi so on complete shutdown it goes dark.

Of course I was originally talking about Matrix-LCD display on I2C and still request it for that type of display.@
MaxJewels captured the request and bend it towards his direction.
I have no problem if the feature will be implemented for both display types.

...
in your case I think the only solution is to put a led directly on the RPI that goes out when the system has stopped
Sorry, I really have a problem with that behaviour.
I made an Feature Request to the nanodlp team.
You can support it, make additional proposals. But its not ok to turn it in a complete different direction and as I asume that you are not a member of the nanodlp team it's also not ok to answer for the team.
Support the request in the way it was originally addressed or make your own request and let the nanodlp team reply on this one
