I am using the dashboard component to compose a page and give the user the power to customize it to their needs. But the list of items its too long and the user experience searching for the specific widget is a bit tough. So I am wondering if there is any posibility to modify the pop up menu that appears when adding a new item, so they can be grouped and going through a tree selector to choose the desired widget; or in other case if can be shown a custom menu defined as a view in the designer that handles widget selection and returns the view of the widget selected.
Thanks in advance!
