On the surface it may appear to be a theme just right for a webmaster to adapt simple changes for his/her site. But it is way too complicated for that. A good example of my frustration is to add to the footer credits. My current them running 3.8.1 was written in 2010 and conforms to WordPress 3.8.1 and its Appearances menu. A simple menu item titled Footer allows me to enter the footer code I want. But not with Customizr. Somehow it blocks the 3.8.1 Dashboard item and instead I have to use a "code snippet" which I found on the theme's site, which doesn't work correctly anyway. Looking at the list of "code snippets" provided, many are simple tasks that in other themes can be changed by adapting CSS statements or typing in HTML in a child theme page.
I've spent a lot of time attempting to get this theme to match my current site (I'm changing because I want to go responsive) but I'm going to look for something else.
