Actually, if I had one piece of feedback for the developer, I would consider separating out the “menu sync” functionality from the rest of the plugin. This beautiful drag and drop interface with nested children is exactly what I am looking for and I’m excited to use it. I can’t imagine using the menu sync feature myself. I’m sure other people do. Perhaps a business model where the core plugin is free & additional functionality like that is part of a paid extension pack, similar to how Advanced Custom Fields works.
I checked the “Hide Menu Sync Checkbox (Currently Disabled)” checkbox, but I still had to hide the “Add Link” and “Menu Options” buttons with CSS.
Since I would like to rely on this plugin long-term for client use, I would gladly pay a premium to know it will be updated to support new versions of WordPress as they’re released.
