I agree with AnuPpuccin + Style Settings beign an amazing combo, been using Catppuccin for a while before discovering that wonderful theme.

Seconding Things 2- I migrated to Obsidian from Vimwiki and already used a similar notation for my bulleted lists. Things 2 Lets you make lists with custom icons that you can use to add bullet journal style meaning to short lists and it is very concise- plus when I open the files in a raw markdown editors the symbols and legend are still somewhat readable.
