Hey @LWyrn !
Looks really nice! And I’ve been working on something very similar and have published it, seems like you’ve already implemented a few of the ideas that I had, have a look at @hakit/core and @hakit/components published on npm, maybe seeing as we’re both working on something similar we can take it to the next level by merging both projects, I welcome contributors!
I still have a lot of ideas in terms of the layout controls as you’ve already done, theming capabilities, and an easier way to use this with home assistant for people who just want to use the components but don’t understand react
Feel free to reach out to me on girhub discussions or through here 
Also, interested in seeing your code! Have you managed to “save” the layout changes or is it just remembered through local storage?
Here’s my post on my react package: Home Assistant React - Component Kit @hakit
