The Automatic List Styles plugin enhances the visual appearance of ordered lists in Obsidian by automatically adjusting their style based on the level of indentation. This feature affects only the read mode, providing a variety of default styles such as decimal, lower and upper alphabetical, roman numerals, and different bullet styles like disc, circle, and square. The plugin helps organize and make multi-level lists more visually appealing without impacting edit mode. Though customization options for list styles are planned, the current functionality focuses on automatically shifting styles as per list depth, improving readability for users.
