👨‍💻 UI Enhancements

The UI should be a bit easier to navigate now, and more user friendly. Especially for new users. (Thanks to @amperag for the suggestions #268)

🎨 Content classes to note body

It is now possible to specify css classes you want to add to a note's body class. (PR by @uroybd #277). This requires the latest version of the template as well. See https://dg-docs.ole.dev/advanced/note-specific-settings/#body-classes and https://dg-docs.ole.dev/getting-started/04-appearance-settings/#css-settings for more info.
