These widgets have functions, so if your system does not exist, the widgets can be reconfigured ..
* For example: if you click the icon for contact and do not open, just reconfigure and direct role for the correct app.
I use Lightning Launcher, ssLauncher, Nova Launcher also will work ... (Nova Launcher more limited) ..
1 - Place your launcher in "free mode" (Lightning Launcher) or 5 columns x 10 rows. (Others Launchers).
2 - Set Launcher Scrolling is "Vertical mode"
3 - You need to install Zooper Widget to use these widgets.
4 - Use Option "pin" to secure the first two widgets.
5 - In Launchers (Lightning Launcher & ssLauncher), there is an option to move the widgets front / rear), you have to set in order, the first widget (top), the second set to be below it, and so on , to have the shadow effect ..
