Nice to see this as a proper theme (nothing bad about the original topic, but it’s nice to have things in one place).
But there are a few things. First is that regardless of how you install it, it’ll be annoying if you choose to customise it and there later are updates to it. If you just use the .json file, you’ll have to update it manually and if you pull it from GitHub, updating it will override any customisation.
I have no trouble with it myself, I am mostly just pointing it out in case someone comes across this and doesn’t think about this (though at that point, would they scroll down to read this?).
The second is that the current implementation of the home button/link doesn’t work, at least not as far as I can tell.
But still nice to see this. I am going to have some fun toying with it.
