If not, I see it working as follows:
1. You link your email addresses and verify each of them by loggin in. vaksel@domain1.com, vaksel@domain2.com, vaksel@domain3.com.
2. On the email, you now have a drop down box. With all the emails and number of new messages for each.
vaksel@domain1.com(3)
vaksel@domain2.com(1)
vaksel@domain3.com(0)
Link another account
3. When you select an email account, it seamlessly switches from one account to another.Something like this is necessary, I have way too many emails and its next to impossible to check them. Yeah I do the ghetto thing and forward them to a single account, but this way would be way more organized.
