The X Pro theme from Themeco is their advanced version of the X Theme sold on Theme Forest. It’s mostly the same theme, except the ability to build custom headers and footers.
There are currently no active X Pro Theme Coupon or X Pro Theme Discounts available.
If you want to enjoy using the tools you own, that you have to work with each day, then the X theme may or may not be for you. They had a huge first movers advantage but I think they could have done better than building a second complicated interface.
