THIS IS HOW
Bubble Cloud Widgets work well with Floating Wiget type apps:
►Smart Task Launcher
►Floating Widget
►Overlays
etc.

Just make sure to double click on the widget after setting its size, then the red/green circle activates “Measure mode” and you are basically all set.

Measure mode is necessary, because many of these widget apps don’t report back the size of the widget (they don’t expect dynamic widgets like Bubble Cloud is).
