As you have noticed, Alyeska currently has framework v2.1, and the features you’re asking about are for v2.2. Currently Jump Start is the only commercial theme available that holds framework v2.2.
We’re currently going through and updating all themes on ThemeForest, but this is a very big task. So, you’ll see these features in the next version big update for Alyeska, which will be v2.2 (matching version number is a coincidence).
Note: You can always see what framework version your theme contains by looking at the bottom of your Theme Options page.
