I know this is off-topic but improving drag-n-drop caught my eye. Currently the windows get focus upon dragging. This makes it difficult to drag and drop in some situations. (Check the video.)
I propose two solutions:
1: Change the focus event on windows to Mouse-Release from Mouse-Click.
2: Make a window focus while on mouse hover if dragging.
