> I regret the decision having gone fully digital, which can only be a complement to physical books.

I've long thought the purchase of a book should be considered a licence: you pay a little more if you want a physical version too, but they're not separate things; the digital ebook comes free/is the basic way your licence can be exercised.

(Ideally licenced people would be allowed to order cheap replacements if they damaged the physical copy, but how would you stop fraudulent sale & continual replacement-ordering.)
