Lotion — A new infinite canvas design app that is simple, familiar and powerful. I started developing my own design tool using web technologies about a year ago and I will be posting progress updates here on posts.cv.

The app is still missing some core features I want to add before making it public for others to use or test (also UI is almost non existent atm.). In the meantime I will be posting some progress updates and hopefully get it out asap.

I actually REALLY like the monospace "just the keys and values" UI, I could imagine a lot of contextual controls that appear next to the object (similar to dimensions) rather than some far off sidebar

Strongly agree. My plan going forward is to keep the content in the inspector as is, because it contains every information about the node but then focus on overlays as a convenient way to configure certain properties or groups of properties (border, radius, bg, rotation, etc.)
