I'd just take a look at some patches out there. There's a lot of usability tweaks existing for acme.

however I still think acme is a conflagration of confusion. It has programs, inside of it, it's a text editor, a terminal, but breaks the interface of /dev/draw so it doesn't properly multiplex by rio.

Often stated, and I imagine to be true, acme was to be a full replacement for rio almost, but it ends up falling short of that.
