I am making a start on widget development, and have developed and deployed a widget after several false starts. After a false start attempting to deploy a faulty widget, I removed the widget folder from the widgets parent folder, corrected the problem, and then replaced it. I now have four copies of this widget in the builder. Two have an icon (one is a copy) and the other two do not respond and have no icon.
How do I clean this up by removing unnecessary or duplicate widgets?
