[Feature Request] Allow for separate "recently opened" per device

[jlfranklin]

I have the Kobo app on my phone and tablet, and multiple Kobo devices including the Clara 2E and Clara Colour. I'd like each reader to have its own "currently reading" book so I can have different eReaders for reading different books. For example, the tablet may have a CBZ open while the Clara 2E has a professional development book and the Clara Colour has a cooking book with color photos in it.

When syncing:

• Do sync the current page of a book across all devices
• Do sync the annotations
• Provide an option to not sync the (first? all?) books in the recently opened list and the default book to open on wake
