@Emil Uzelac -
Sorry if my comment is sounds like 'a baby wanting a candy' and too noisy. I know (at least can imagine) how hard and careful each improvement on the theme development you do every day.

I just trying to deliver my idea about the theme test data, and honestly aware that I just a BIG fans of WordPress and never contributing anything on the development. I understand that my idea is far away from realization.

Sorry Emil.
