Is your feature request related to a problem? Please describe.
I love how the books are sorted by Date added as default. However, this does not seem to apply to books added to a shelf and I wish it would behave just like the admin view. Right now, I have to go to the shelf, activate manual sort, then scroll all the way down to select the book and drag it all the way back up. And finally scroll all the way down to Save it.

Describe the solution you'd like
Simply mirror the behavior for the full book list also for the shelves.

Describe alternatives you've considered
Alternatively, add a sort button to allow sorting by date added to all views/shelves

Additional context
not really needed.

Thank you for making this amazing utility!!!
