They’re solving a real problem users have, but nevertheless it’s amusing that a format used for its rigid layout and reliable typography is getting fluid layout and customizable typography. And the format is so ill-suited for this purpose, that it requires “A.I.” to achieve it.
Ugh. Just what this ubiquitous and horribly overextended format didn’t need, more dubious “features”.
It’s presented as “new stuff on PDF”, but reading it again gives me a different impression: it feels like “new features in our PDF reader”, but not necessarily any changes in the underlying PDF. It might also do some tweaks to the latter, but the text was ambiguous on the matter.
