I have a large number of keyword bookmarks in whichever browser I happen to be using at the time that I’ve been building up over the years1. One of the ones I particular enjoy is
data:text/html, <html contenteditable>. What that does is open a new tab where I can take notes, completely locally. It’s really handy… but there’s one big problem: I often accidentally close the tab and lose whatever I had been typing. So I decided to take a few minutes to write up a simple extension of the idea that would save the data to LocalStorage.
