Just an idea: being able to set the Print status from "Ready to Print"

Just an idea:

being able to set the Print status from “Ready to Print” to “Printing” so the App can continue to display the print Status after a lost connection.
maybe with a long Press on the Printer Icon in the lower right corner.

I use a normal Ventilator wich i turn on munelly after the first layer is finished, and turning it on or off looses the usb connection

when printing from SD card ?

Yes

+1 for recreate print status notification on reconnecting while printing via sd!
