On the Special:Nuke / Mass delete function the selection toggle [Select: All, None, Invert] is too close to the the delete button
and it is possible that when trying to select "None" that the delete key can be hit (especially when environmental factors work against you).Further separation between the delete and the selection toggles would be highly beneficial.
In fact there are some stylistic issues that are probably worthwhile reviewing on the page against the current design schema.
