I like shortcat, but it's slow, even on a modern Mac.
Also, I'm not sure the dynamic nature of the hotkeys is a good thing. I could imagine if you use Mouseless for a long period of time, muscle memory might prevail as screen locations map to the same set of keys.
Some apps have crappy accessibility so Homerow doesn't always work in some apps. so I kind of want to try mouseless as well. I might end up rocking both at the same time.
