Launch-X Pro - Stack widget?

[codpiece]

Hi,

I just discovered Launch-X Pro and I think it's really a great app (well, widget)!
In case you don't know it check it out: https://play.google.com/store/apps/details?id=net.yuvalsharon.android.launchx.pro
(there is also a limited free version: https://play.google.com/store/apps/details?id=net.yuvalsharon.android.launchx.free)

Anyway, in their screenshots they show a stack widget which looks cool, but in the app I cannot find how to enable it? Someone can help me?
Do I need to download something else?


Thanks!
C

Maybe I figured it out...is it possible that the problem is that I'm using android 2.3?? Maybe I need android 4 for the stack widget? Can someone confirm?
