Give admin the ability to disable/enable "customer" email column from the affiliate commissions page.
I would prefer the email to be replaced with the customers first name or just the country/city/state it came from. Even though it doesn't display the full email I would like a name or location better than an email slightly displaying to affiliates due to customer privacy concerns.
Would also like to see the affiliates commission percentage and the total sale (not including tax and shipping, just the product sale price) that was made from the customer they referred in columns on commissions page. This way the affiliate can see what percentage they earned along with the total sale rather than just the amount they made.
