Witchcraft: JS/CSS injector

Witchcraft loads custom Javascript and CSS directly from a folder in your file system. Think GreaseMonkey for developers.

Witchcraft is a powerful Chrome extension that allows developers to inject custom Javascript and CSS directly from a folder on their local file system. It operates similarly to Greasemonkey but is designed specifically for developers, facilitating easy customization of web pages by matching domain names with script files. For example, if you're visiting https://www.google.com, Witchcraft will automatically load google.com.js and google.com.css from your folder, ensuring your scripts work across various domain levels.

Unique to Witchcraft, there's no need for any page reloads when scripts are edited, allowing for a smooth development experience. The extension supports both Windows, Mac, and Linux environments, automatically handles Javascript and CSS, and even includes an @include directive for loading additional scripts. Whether you're a seasoned developer or just getting started, Witchcraft offers a seamless way to enhance and personalize your web browsing experience. Visit the website to learn more!

I had trouble setting it up. I followed the instructions as best I could and then reached out to the developer with a descriptive inquiry, inclusive of images. No response. Nonetheless, I can't knock the app too much because of my technical limitations. If I could get it to work it would be significantly better than tampermonkey.

I can't believe I was using Tampermonkey for so long as this is clearly better by a longshot.
