I use them constantly, immediately categorizing emails as they come in (prefer this over Smart boxes).  Right now I am using more than 4 regularly, however there is a default "last four" categories on the pull-down menu, which in my case I find cumbersome.  Is there a what to get rid of these top four?  I know in an earlier version i didn't see it.  Maybe there;s a setting i inadvertently set.  Anyone who can help?  Thanks!
