Gala should support better window tiling [$25]

Elementary's Gala is awesome. I find it lacking in one aspect, the window tiling. The "*Ctrl+⌘+Left/Right* Snap Window to Half of Workspace" part is good but not great. Need more tiling features, something like the Num keys snapping windows like in Ubuntu Unity or soemthing like this Gnome-Shell extension https://plus.google.com/112759940931397244391/posts/NHCdTj5LpTP . Makes working with multiple windows a breeze. :-)
