Unless I missed it, there is no setting to display the acutal DKIM selector being used.

I mainly use this plugin to validate emails send by servers/websites I host, and seeing a (No DKIM key found in DNS server)-error is only partially helpfull. Seeing the selector that is being used to sign the email without having to look at the source code would help a lot.

The selector should probably be list in the popup
