I like the new PDF help file, it's definitely an improvement

But..there are 3 concerns that I hope you will be able to address at some point:
a) Blank pages occurring now and then - no biggie. PDF isn't secured, so could probably remove them myself if you're cool with it.
b) ToC is linked (possible to jump to each subsection), but Index is just page numbers - a bit of a let down, would have been icing on the proverbial [navigational] cake.
c) Lack of visual aids, like screenshots - not so much of an issue with CHM help, since you can't scroll from top to bottom of the document. It gets a bit mundane and hard on the eyes to see page after page of pure text. An administration guide 3 times the size is easier to read because it has screenshots, diagrams, tables, etc.
Some of those could be limitations of that software, so some feedback for those devs
