I might sound like a crotchety old man but I'm kind of tired of these JS and local storage browser apps. The tech is still just as clunky as if I were using a text file on my computer except you now require a browser to use it and run the risk of clearing your local storage or somehow corrupting it and losing everything, whereas local files a lot easier to keep track of and backup. At least that was my experience with laverna which this reminds me of.

Trying to emulate an offline app via a browser seems flimsy to me.
