I use the script a lot but I must admit that it's not user friendly. I recently had to use it and I almost wept - there was no easy way to specify the file to be loaded, and very sparse instructions or explanations.
That day I learnt some valuable lessons about the craft of making software. I learnt the importance of good documentation. At the very least there should always be a clearly written README with screenshots if possible. And if you are building a tool that runs in the terminal, or a CLI it's important to give hints, and provide help pages etc.
But I digress - the realization that my app is virtually unusable made me think of converting it into a desktop app.
The way Electron works is it sort of combines Chromium and Node.js enabling stuff that's not possible when using either on it's own. This property gives Electron incredible power because it's then possible to use Node.js features like filesystem and OS access while at the same time having access to DOM features and Web APIs.
The app I'm building is called Nota (Latin for Notes) and it'll live in this Github repo. I'll be committing and pushing to it as I go.
