I agree as well that the "None" should be a configurable setting but I
recommend this setting be implemented as an admin setting in the admin
console that an administrator would turn off "None" across the entire
report suite rather than report by report. Also, when "None" is
configured to not display, it's respective metrics should also be
removed from being totaled as revenue and orders due now for example in
the Search Keywords - Natural, Search Keywords - Paid and the Customer
Conversion repo...
