While there is some documentation for exporting OSC devices for later use, there is nothing on how to import them, or any mention of whether this works for other types of devices, while the user is able to export any type of device.

furthermore, maybe we can add a QPushButton to import device

proposed doc section :

Importing a device

1. Go to default library path under settings > library
2. Add saved device ending in .device
3. The device will be imported and appear in the right panel under OSC devices.
