I have 6 imap'd email accounts setup on my n900. Works a treat.
However when an email comes in, I see the light flash, I hear the incoming alert, I see the email preview. But which inbox has it gone in. I must be missing something but right ow I have to go through each inbox trying to figure out which one the email has turned up in. It would nice to see a little identifier next to each account that has recieved email since last read.
