Build in an EPUB Reader and Allow for EPUB Embedding
The Reader app (all platforms) should be more generalized to allow "reading" of both EPUB or PDF documents.
Similarly, we should be able to embed an EPUB into a PDF file. (PDF has a robust method that allows it to embed other file formats.)
Then, we should have a switch in Reader that would let a user to switch from PDF to reflowable EPUB and back again.
While I understand that Adobe is investing heavily in Liquid Mode, this EPUB method would be far more reliable for people who need to control the design of both static and reflowable modes.
Thanks for reaching out to us for your concerns.
We have no immediate plans to work on this FeatureRequest.
We will let you know if this get prioritized for our Future versions.
