Is your feature suggestion related to a problem? Please describe.
I was directed here from this discussion. I've been a heavy user and fan of Contexts. Unfortunately it's no longer in development (though works fine atm).

To quote that discussion:

One of my favorite features is quick switching by holding down Caps/Esc and typing some of the Application / Window name. It'll be fuzzy matched and when releasing Caps/Esc, the selected window will be focused. So if you know the window you want to switch to, it's extremely fast.

And mindfulhack responded:

The dev is currently extraordinarily dedicated to responding to tickets and is in heavy development.
I've already helped out and contributed a bit. Recommend to start Github issues for any gripes right away.

To the extent that's something you think would fit into the vision of this app, I find it invaluable.
