It would be cool if we could use swiping inside a widget container in order to create more space for the widget content or even mock up the functioning of stacked widgets. This way we could design widgets that display more content when we swipe to the left inside the widget.

You should look at/try out KLWP
But, but… But I want a widget not a wallpaper 
LOL
I get that, but swiping/scrolling is an animation, which isn’t available in KWGT…
