Currently, when widgets are placed on the desktop, their position is remembered as a fixed pixel coordinate.
With my computer being a 2-in-1 that I frequently plug into an external monitor, this results in widgets being in different places when in landscape, portrait, or the external screen.
An option to align a widget in a relative fasion would be nice, just like the panels: centered, far left, left/right third, top, bottom, etc.
That way widgets would stay visually organized as the screen size and orientation changes.
