Please put this box back at the bottom, that's where it belongs (you want people to give a reply AFTER they have read the other messages, not BEFORE).
Also I don't like the Home icon, it simply doesn't make sense. It's much easier to use the keyboard.
Finally the Quickedit shouldn't be a radio button. This is against user interface conventions. A radio button is used to make one selection from a predefined set of options, not to initiate an action. If you want to introduce something like this function then simply make it a button near the regular edit button, that's the location and the form it should have.
Sorry to sound nagative, but in my opinion these changes really don't make sense. It looks as if the major reason for these was a programmer trying some fun things, instead of providing a better and clear interface for users.
