Couple major issues

First, when Forwarding a message you cannot edit it! Silly that I am forced to include the entire forwarded message and all its headers in the forward. Next, the ability to perform multiple actions on a set of selected messages (for example, select 10 messages, mark as read, and update their label) is gone...now I have to select the message again for each operation.
