    Note that due to returning the created figure object, when this funciton is called in a
    notebook the figure willl be printed twice. To prevent this, either append ; to your
    function call, or modify the function by commenting out the return expression.

Obsidian SASS theme switching tools

I was building up a small library of css snippets, and mixing and matching via copy-paste was getting tiresome.
So, I knocked myself up a little solution using https://sass-lang.com/
To use this solution, you need to follow the instructions on the website to install the SASS command line utility.

Instructions

For my purposes, I created a subfolder in my Obsidian vault called ./.themes where my obsidian.scss file lives. I also created a subfolder for mixins (./.themes/mixins) containing small snippets like "Andy Matuschak" mode and collapsing sidebars (and my preferred custom colours for my Base2Tone theme)
