This is in fact not easy because of other "features" that come along with it. I must "target" a later release of Android, which will break passing books to reader apps (see
https://www.mobileread.com/forums/sh...d.php?t=295599). I must work around that problem before I can consider anything else. I need to do this before the end of the year or I won't be able to release CC updates.
It is worth noting that "fixing" this problem also requires enabing multi-window, yet another can of worms. I don't have a 2:1 device, much less one that can do multi-window, which is concerning. I don't want to introduce features that I can't test.
Bottom line: someday, maybe.
