I just downloaded the K65 reference manual, a mighty document with >2000 pages.
It doesn't come with PDF TOC/bookmarks.
Personally I'd immediately be put off from using NXP offering if I had a choice of using, say, Texas, NXP and Renesas MCUs a completely random example. Jumping back to the beginning of a huge document to access the TOC is not fun at all.
Plz fix or do something. i.MX 7 series for example has perfectly good PDF TOC.
