If the code were static, it'd be easier, of course. You can't have it all: decent backend configuration, dynamic code and pages, flexibility, and source code that fits into a single, small and easy-to-read file...
So, I wouldn't expect it to be "less complicated" with BS3 options, but rather more - if it meant all options, standard/BS2/BS3. But you should notice that it's getting easier as you continue working with it. Again, common sense and proper search tools/strategy are your friends.
Edit:
As for your example, it's hard to impossible to say without a link to a live site. See also
