There is currently the ability to change payout details but not to see what your existing ones are without starting the process of changing them.
It would be good if a partially obscured summary of payout details was available so it was easy to confirm that they are as expected. Date last updated would also be a valuable piece of data.

I've recently become an affiliate and set up my details last night. Today I've received an email saying my details recently changed, but I didn't have a way to see if that was referring to my creation of the payment details OR whether my account had some degree of compromise without going through the setup process.
