awesome is great. one of the few tiling managers that actually has the grace built in to deal with windows that really can't be tiled sanely.

Curious, if a window refuses to go under a certain size, can't it be tiled using its minimum dimensions, and the rest of the layout adjusted a bit?

awesomewm is great and pretty stable. I have been running it by default on all my machines since 2014 with very little changes and almost the same config.
