MMW - Adding custom emojis as icons
Adding custom folders and note icons could be difficult. Quartz supports adding emoji prefixes to folders and notes, but I'm unsure if that equates to svg icons.
A workaround could be using FontAwesome to create custom emojis, and replace standard emojis such as 📁 or 📄 with bespoke Morrowind-styled emojis.
If implementing emojis, it's important to consider how to make emojis accessible to everyone.
