Post update most things seem to be working. I am a heavy Gmail IMAP user with 3 different accounts setup through Mail. One BIG exception:
ISSUE:
Inbox Label Still Appearing on messages moved to Trash
Deleting a message from Mavericks Mail (using either the Delete key, dragging the message to the new Trash icon in the sidebar, or clicking the Trash button in the toolbar) results in the message properly being moved to the Trash folder, HOWEVER, if you view the message in the Gmail web client it still has the Inbox label attached to it (even though it is in the trash).
This doesn't seem to have any effect on the message showing up back in the Inbox, or any affect on any other Apple Mail client (iPhone iOS7, iPad iOS6), but could be a long term issue if either the Mavericks Mail or Gmail itself decides to read that Inbox label.
Any suggestions or other users with the same issue?
