Addressbar Outline/Frame Color

I’ve posted this on the reddit sub too, and basically am just wondering, when you click into the address bar, it becomes slightly orang-ishly framed. I’m a bit confused about the response on the reddit post, but my experience is that there is no way to change this, so i’d like to suggest this feature.

Also, btw, if anyone knows how to edit themes, i tried editing the manifest.json (of course deleted the Chached Theme.pak file) and even deleted it, but the theme didn’t change, or become nonfunctional for that matter. Is there somewhere another copy of the config file?
