The speed issue is even more pervasive -- compose, but also labels (if you use L to label emails a lot, you have noticed it). Two questions, if you do not mind -- (1) Does FastMail offer threaded email conversations? I cannot stand the left/right pane display of email UIs like Outlook (or Apple Mail). (2) Does FastMail offer labels and filters that come close to those in Google Mail?
