The annoyances here with Adobe's latest version still is when going to load the online user manual in pdf format for any particular board in order to review specifications. You see most of the front page but wait while the rest loads and finally are able to scroll to wait again while more loads.
It would be interesting to compare foot notes when Sumatra heard of before here is tried out for something like that. The download there is a beta version for the moment just to add here.
