Unable to tell which email received new message without clicking through each one to find it.

I have 5 different email addresses I use for work/personal etc. When a new email is received it does not not highlight which email on the list received the email. Is there anyway to do this? (ex. Thunderbird would highlight the email address that got the message and put a little mark next to it)

Sorry, this is not possible at the moment but I will add it to our list of features - it is a reasonable suggestion.
