I just discovered this mod and I love it! I think it's an upgrade to the mod I'm currently using, Cursor Enhancements(https://mods.factorio.com/mod/CursorEnhancements). Your mod has a GUI that allows for easy customization, which is a great feature. While Cursor Enhancements also has a similar feature called "scrolling override settings" that allows for custom swapping, the modder removed support for it after version 2.0, so I really want to use your mod as a replacement.
However, I do hope that your mod can also have one feature that Cursor Enhancements has: automatic ghost cursor. Currently, if there's no corresponding item in the inventory, the mod will skip it directly, but I would like it to become a ghost item instead.
Additionally, I would love to have an option to disable the settings icon in the top left corner and provide a shortcut key, as this would make the game interface cleaner.
