New .Mac Webmail
I think it’s weird that it looks so much like Apple Mail, because it doesn’t act very much like Apple Mail at all. For example, yes, you can drag-and-drop messages in the new .Mac Webmail, but you have to click on them to select them first; you can’t use Shift with arrow keys to select multiple messages, etc. These are hard things to implement in a Webmail client—but if it looks this much like the regular desktop Mail, it ought to act more like it, too.
