Looks pretty -- but the great thing about man is that it runs right there within the terminal. Switching to a GUI browser is a big mode shift and comes with all sorts of distraction. Using a terminal browser like links is probably pretty clunky.
Running in the terminal is the biggest advantage - moreover the terminal man-pages allow forward and backward search with vi-shortcuts, which makes searching them really easy and fast.
The biggest improvement the web interface offers seems to be the outline on the right. For long man pages (man bash, I'm looking at you), that could be very useful. Anyway to do that in regular man?
True, and I agree. Man is great to pull up in a terminal when you quickly need to look up something.
However when you're spending hours reading, scrolling and jumping all over a man page like I've been doing with tmux the last few days, smooth scrolling of a web browser is nicer. And the right-hand section outline helps too :)
What I'd like is something like this that would also try and gather up stuff from info and /usr/share/doc/PROGRAM/ or whereever it is on the current system and possibly even online docs and try to present them in a reasonably consistent fashion, or at least have it all accessible in one place. But that's a little more ambitious. Also it'd have a terminal program that was a shortcut to remote open a tab in your browser and focus it. The latter would be nice for this.
