I love the ability to stay in a page/section and switch between subaccounts while remaining in a section.
After i make a update in "Email Settings" for subaccount (lets call it SubA1) I switch to a different subaccount (SubA2) but the domain/email settings info for SubA1 still shows.
I can resolve the issue when I click to a different page in the sidebar menu for SubA2 and then click back to Email Services.
