Do you use floating apps on your smartphone?

These let you pin notes, browser, calendar, video player, calculator and other resizable windowed apps on top of everything else, aiding multitasking with your handset significantly, especially if you have a larger display. Well, Android's versatility is here to help, too, even if you don't own a device whose stock interface supports hovering apps. There are 3rd party apps and mods out there that allow you to "float" videos, a note list, calculator, even browser windows and whatnot, above anything else you are doing underneath. 

Needless to say, this aids significantly with multitasking on your handset or tablet, as it lets you see and do more things at once. While not exactly a multi-window mode, "floating" apps can certainly come in handy at various situations, so we wanted to ask you if you use such applications on a regular or semi-regular basis, or if at all.
