This is a set of mockups for the improvement of the Moving, Resizing and Layouts handling of windows in Kwin.
Core is the ideal that Kwin needs to release the window content from being interacted with and let Kwin hijack all input temporarily for the express purpose of resizing or moving the window with keyboard shortcuts.
Secondary is a simplistic tiling layout per desktop, and how that would handle the different inputs (Move/Resize/New Window) and how that compares to Stacking styled layouts and differentiates compared to Manual Tiling.
