The new Map Widget offers a drag and drop location mark management allowing you to fine tune your map.
To organize your map locations you can change the order of them. This is helpful when you're using the draw line between locations option.
To change the order of your map locations (you have to have more than one location) click the "Organize Locations" link on the maps edit page.
You can now change the order of you locations by changing the number in the "Sort Order" column. Note: there is not a click and drag option.
Once you made the changes to your sort order click "Apply New Ordering" then click "Save" to save the changes.
