I have an IMAP-Account with a lot of folders. I have always to use my mouse to switch to the next folder with unread mails.

It woul very helpfull, if evo would ask me, if he should switch to the next folder with unread mails when I press "next unread mail" and there were no more unread mails in the current folder.

something like this:

if ( ! unread mails in current folder ) && ( unread mails in other folders ) {
  open dialog "There are no more unread mails. Should I change to $nextfolder?"
  if ( answer == yes ) {
    switch to $nextfolder
  }
}
