[Feature Request] Allow selection and actions in Books view

[mblennegard]

Is your feature request related to a problem? Please describe.
Currently there is no way to select and perform actions on books in the Books view.

Describe the solution you'd like
A button or similar to enable selection in the Books view.
When one or more books have been selected, the same actions that are possible from the Books List view (e.g. Merge, Delete, etc.) should be available via a context menu or similar.

Describe alternatives you've considered
The Books List view allows selection, but since that only provides a list and no book covers it is much harder to find the books one is after to perform actions on.

Additional context
None
