Phantast, also for letter O)... the copy and paste lets you copy the dial values for one item and paste it onto another item. Lets say I have a cube and a sphere in my scene and I want them to share the same place...I select the cube, copy, select the sphere, paste, and now my sphere will share the trans, scale and rotation values of the cube.

To add to your list:

Q) a toggle for each material that will let you decide whether or not you want an item with transparency to display as solid or dithered. I don't mind the dithered look when working with clothes or items like glasses, but for transmapped hair, I'd rather it look solid until it has been rendered.
