Swipe from the side to activate a widget overlay? Have looked in various places, googled, looked on the play store, etc., but so far I've been unable to find an app or other way to do what I'm looking for, which I'll describe here:

I've been using various apps over the years that let me swipe from the side of my screen to overlay a series of shortcut icons to different apps.  Currently I use Smart Task Launcher.  However, I've recently started using Bubble Cloud Launcher for my Androidwear watch, and it also has the ability to create a homescreen widget that provides an easier/more dynamic way to set up icons.  But Smart Task Launcher doesn't allow for launching of widgets via a swipe.  Well, it's supposed to, but an error is produced when you try to set it up.  Does anyone know of an way to do this - swipe from the side of the screen and a widget of your choosing gets displayed as an overlayed "screen" on top of whatever you are currently on, whether an app or launcher screen?
I am the developer of Bubble Cloud Widgets. I tried, and it is fully compatible with Smart Task Launcher, but you have to invoke the special "Widget Measure Mode", since STL doesn't report the widget size correctly.

Here, I shot a video for you:
