That’s quite a clever solution to toggle modes! This and the Pisum theme’s ability to use Andy mode in the light version are both ingenious in their own ways. The mode switching to toggle seems quicker since it works with a hotkey in Obsidian and requires no 3rd party app. But your solution seems more flexible. In fact, I think it can be extended to even switch themes entirely by picking a random one from a folder full of Obsidian.css files. Imagine having a new theme everyday! That or different colours for each day of the week. The possibilities seem endless. Thanks for sharing!
