/* -------------------- Fixing Code View -------------------- */

/*
Trilium uses Code Mirror. Code Mirror has themes!
Code Mirror Themes can be previewed here:
https://codemirror.net/demo/theme.html
And the relevant code in their github, for example here is "material darker":
https://github.com/codemirror/CodeMirror/blob/master/theme/material-darker.css
We can't use this straight away in Trilium, we have to adapt it from the prefixed codemirror subtheme to the "default" code mirror theme Trilium expects. A find and replace like this does the job:
.cm-s-material-darker” to “.cm-s-default”

Hooray, now we can directly control the code theming!
