Where has this plugin been all of my WordPress life?

Outstanding! Just now getting used to it, but I have found no real issues with it. The only problem I see is that there’s some compatibility issues with my theme ARK. When I do adjustments to font or colors they don’t take and just stick with default. That’s not really a big problem for me. There are simple work-arounds. Outside of that this plugin is one of the best I’ve ever used.
