Came here to say my thanks, playing with colors is much easier the way you put it. Instead it's maybe more convinient to just do console.log or alert so user can copy his theme manually and paste later instead of manipulating clipboard? Anyway, if someone has issues like this, just replace |

I quickly hacked together a theme editor that I don't currently plan on adding to Glance but wanted to share as a tool on the side that makes creating new themes much easier.

Demo

Usage
Paste this hunk of code into your browser's console while having Glance open:
