I am avoiding putting Adobe Reader on my system. All I need is reading ability and good indexing. Reader provides more than that and huge updates to go with it.
I started out using Google Chrome, but it is slow loading larger documents & no indexing.
Now I'm using Evince 2.32.0 on Windows, but search is very basic and slow. Also, it lacks navigation using the table of contents. No indexing.
Sumatra (GPL) is fast, but again search is basic. No indexing.
Interested in any opinions on PDF reading.
