alt Hacker NewsIf you want an out of the box test then playing with river-classic¹ is probably a good place to start. It gives a feel for where you can go, without having to put too much effort in.
For example, it has pluggable layouts where instead of pulling in a lua module(such as awful.layout) in awesome you'll run an external process which handles events. You can even run multiple managers and switch between them with bindings, or write a custom one to scratch that itch. If you're happy with just awful's .suit.tile.right and .suit.max then basically any backend will do.
This is why it feels like a reasonable path off awesomewm to me. I always considered awesomewm to be the WMConstructionKit, and while river changes how you interact there is still a nice route to extensibility. The newer direction even more so than the -classic offshoot.
