Yeah, I keep thinking that CHM was the peak format for offline docs. Today we have Kiwix [0] and Dash/Zeal [1] – both amazing projects, but somehow they feel more complex, and the formats they use aren’t as ubiquitous.
The other day I crammed some awful internal docs into zeal. It was a fun time, good format -- was able to reverse engineer it without looking at the specs in an hour or so. I wanted to be able to look at those docs having to remember exactly where they were every time.
Actually I'd go back to CHMs for docs. A modern reader would be good tho.
