I'm building a keyboard-driven editor for designing UI. You could think of it as a weird bastard child of Vim and Webflow. I've been tinkering with it for a while in private, but I'd like to shift gears and start working on it publicly.
The editor itself isn't available yet, but I've got a Github readme that explains the concept a bit more: https://github.com/matry/editor
Eventually I'll do a ShowHN, once I get a stable version that I feel comfortable demoing.
