This plugin adds highlights for text filetypes, like markdown, orgmode, and neorg.
- Background highlighting for headlines
- Background highlighting for code blocks
- Whole window separator for horizontal line
- Bar for Quotes
Treesitter grammar needs to be installed for the languages.
Use your favourite plugin manager to install.

}To change any setting, pass a table with that option. Or add a completely new filetype.
You can turn off highlighting by removing that part from the query, or setting
highlight to false.
