I've grown quite content to use a label in lieu of a marking a message with a proper flag, although I'd certainly like to double the number of labels available.
One bit of weirdness remains, however. My browswer is sorted by label so that those I marked Urgent appear at the top. The browser sub-sorts by date, which is what I would expect. However, once I've unmarked a message, matching its label state with the others in any given window, those unmarked messages float to the top of the stack of normal messages, regardless of their datestamp. What I end up with is a list mostly, but not entirely, sorted by date. Is there any way to fix this? Thanks, z
