In general it would be way better to be able to fully customize the layout manually.
I would like my widgets to be aligned to one side, and not split themselves evenly between columns, as in for example having one column in the bottom-right be date and weather underneath, a speed dial in the bottom-left corner, and on top of that the mail widget in the middle of my screen.
It not only would allow me to properly organize my widgets, but also arrange them to fit with my background.
