I think my use case for the
Unplugged PI, IIRC, was to keep the Kindle connected to the usb port while preparing the books for sideloading, like... for instance
- convert to KFX;
- transfer to device;
- see if conversion went ok, opening the title on Kindle
Those steps were so frequent that it became more
comfy to just click the Unplugged icon, instead of disconnecting and reconnecting the USB cable...
Well, it's been a long time I used it, so I really can't remember
how to explain why exactly the PI was needed
