I've often found myself pulling the SD card from my laptop, whacking it into the um2 and setting a print off, all because I'm too impatient to wait properly lol...but
Now that there is a pause feature we can make use of, a great little feature would be the ability to load a build queue into the printer.
So the print is running, I hit pause, remove sd card, load sd card into cura, add new model to sd card, reinsert back into printer, add new model to a build queue and resume.
Just thinking out loud!
