With some of the stuff I've added to my theme, it would drastically simplify if I could access settings. Really, any settings that aren't security related would be helpful.
Like if I could access whatever the user's "Reverse proxy prefix" was, I could compare the active page to the expected latest-comics page, and change the look of the "New" button accordingly.
Or if I could see if "Enable folder metadata display" is enabled, I could show/not show certain things on each page.
Otherwise I've got a list of settings at the top of a js file that need to be manually set before the first use.
