I'd like the request the feature to move pages between books via drag & drop.
I'd be happy with Copy Page, Cut Page, Paste Page functionality within the Page Explorer to enable movement of pages between books.
It's currently very difficult to achieve this, especially with a page that has more than one layer.
I work with one book as a general, ongoing sketchbook and then if a theme develops I like start a new book for that theme and shift or copy the relevant pages to the new book.
Thanks for your feedback on this suggestion Rolan and Steve!
