Button to deselect all selected attributes with blank values

[HarshitRawat]

As part of development best practices , we all know it's wise to deselect all attributes which were selected by default but have blank values. Having a button to deselect all such attributes with just one click would be very helpful. Otherwise we have to manually deselect such attributes for every element we spy

This would be very handy indeed!
