One of the features I really miss from Roam is the ability to move a list item “up” and “down” in the list using the
CMD + Option + ↑ and
CMD + Option + ↓. I believe it would outdent the item if you move it out of a parent list too.
Edit: This feature is available in recent builds. You can customize the shortcut for it in the hotkeys setting. Search for “Swap line up” and “swap line down”
