I sometimes do this as well. Most tiling wms do support overlapping windows thouhg it isn't the default. But then many regular window managers will support placement of windows in various splits manually with a keypress or two so in reality the wins for tiling wms are very small in normal use. I think you have to have a crazy rate of opening and closing windows to benefit from automatic tiling which doesn't fit with my actual usage outside the terminal where I use a terminal specific tiling.

Several times I have tried to move to scrolling as I like it a lot more than tiling.
