I love the new tiling manager, but I find having to press Meta+T, clicking a rather small button, then Meta+T again to be a little inconvenient. It'd be awesome if I could simply drag a window over another window to automatically tile them.

For example, if I have two windows side by side, and I open a third window and drag it to the bottom right while holding Ctrl+Shift, the existing window on the right would automatically shrink to the upper right. Then, if I release the mouse button, my new window would fill the bottom right.
