Listing Emails in left margin

Listing Emails in left margin

Hello, I have 5 pop3 email accounts in my ZOHO email. With the size of screens now a days, you can list more then 2 OTHER email accounts as tabs at the bottom of the "inbox, sent etc column". The rest shows up under "MORE" which is a bit of a waste, considering how much white space is above all of these. Give it 5 or 6 before you show more please! :) 

Thanks
