So it's true, you can nest layer groups with transformation masks within your master layer group, and you can independently manipulate your sub-groups to perform complex animation effects!

Extra hint/advice* If you intend to make a layer group or transformation mask which moves your assets beyond the boundaries of your initial canvas size, example 1920 pixels across, and you wish to move your assets to 2000 pixels well outside of that initial 1920, to avoid some of your layered assets from being clipped, temporarily expand your canvas size via Image/Resize Canvas or Ctrl+Alt+C shortcut, and widen things so your asset grouping *arrows or bolts or bullets in my case* won't get clipped and disappear. You can later re-shrink your canvas size to its prior dimensions prior to exporting your vid or gif set so things will appear normal.

Having learned all this from tonight's krita session, now I'm less hesitant to make hand drawn assets for my pseudo 3D fanart of HHG and animate that cluster fug! xD

Tangent* Having learned that animation isn't as difficult as some make it seem *looking at you Adobe* I wish to expand my skill set by making other short looped gifs and in the future, short vids foe everyone to enjoy!
