I would like one!
From the inbox view, when I select multiple messages, the top bar presents me with the option to "Mark as read" or to "Archive" all the selected messages in one fell swoop. The option to "Move to folder" is not presented.
In fact, the only way I've discovered to file a message from the inbox view is to configure a swipe action (for example, "Left swipe") to do so. However, this swipe action *only* affects the message immediately under my thumb - it does not account for any prior selections, and therefore cannot be used to move more than one message.
