Fields Pane Search Bar - provide a cross (like "X") to clear the typed Search String

When using the Fields pane to search for field(columns/measure) sometimes you have to type more number of characters to get what you want. However, when clearing this search string we have to use backspace to clear one character/number at a time. A workaround is then to select the whole Search string and press backspace or delete. Instead, if you provide an (X) icon (typically found in many search bars ) at the end of the Fields search bar, just simply clicking it will clear the search string, reverting to the unfiltered view of the fields pane.
