You can quickly adjust the order of text in your note. “One-Click to Outline" For clearer organization of your note, you can convert them to an outline with one click. Editing text in the outline provides a clearer view of the structure. Drag and drop is also supported in outline mode, but you drag an entire paragraph. “One-Click to Mind Map" If you find the outline mode still not clear enough, you can convert it to a mind map with one click.
