I don’t think that would be useful for users. A user usually has in mind what goal to accomplish. That goal is not “torrc”, but “make it work” or “censorship circumvention”. Instructions on how to modify torrc to accomplish various goals is documented on various documentation pages.
We do have a support page already.
What specifically does the tails support page do better? Please create a new forum thread.
“if they have read and understood the documentation properly” - As sad as that is, it is an entirely unrealistic assumption. The redirection of support questions of generic upstream project questions to other upstreams was actually done by me to save time and space in Whonix forum.
Side menus waste a lot space and look awful on small screens.
There is a lot room for lots of opinions here. @bnvk, the new Qubes usability designer, once told me, that he isn’t offended by long scrolling pages.
