**Stacks – X** includes multiple unique designs inside of one powerful theme, and we refer to these designs as “Stacks.” There are currently four Stacks available in X, with more on the way. It’s like buying one theme and constantly getting access to new designs all the time! The links below take you to the main demo for each Stack, however we have created multiple unique demos for each Stack so be sure to check them all out. **v3.1.1** – December 23, 2014
