When we ship this in beta 23 next week, you’ll be able to create external packs, load them into Elements and update them on the fly with your text editor of your choice (It’s how we build the built-in components. In the screenshot I’m using Nova).
I’ll do a video on how this all works, and how to move your Custom Components over to an Element Dev Packs next week — don’t worry, it’s SUPER easy!
Have a great weekend, and let me know if you have any questions in the meantime
