Fun little aside: What if a web app was a local utility? Like a little tool that gave you live previews of markdown files as you made changes to them in your regular editor?
Here’s a 30-second demo video of just that in Kitten.
Check out how simple the code is:

(The ability run Kitten apps on random open ports and to launch the default browser is currently in a dev branch; will merge to main soon.)
