Do you know why I always keep my home screen below area blank. 2 blank rows. It's to make sure I have no problem sliding left and right without accidently pressing an app.
I add sliding UP will open my application drawer. It's an additional action and the setting available in Apex Launcher. So you could quickly access your application drawer.
Set Swipe UP and Swipe DOWN action setting here....
Another Apex Launcher setting that I like. Lock the desktop. This will prevent you from accidently removed/change you home screen apps list.
Happy configuring your home screen....and practically for daily usage :)
