This is a theme for trilium. In v3 I chaned the check list text to orange color. I changed primary font to Baskerville. Some other minor tweaks
It is compatable starting with trilium 0.43.3. It will likely function with previous versions
Color scheme is based on gruvbox
See here for installation instructions. You need to add an attribute of type Label with name appTheme and no value. After setting the attribute, you need to select the theme in options. You may need to re-load the front end (ctrl-r).
Switching to another theme does not work entirely without removing the appTheme attribute. I don't know why.
