Comment 4 for bug 2012961

I think my main concern there is that they aren't actual tools like the rest of the list, which switch into a different interaction mode and handle mouse events, etc

A couple other ideas I had:
- Add just one more button, but make it a menu with crop to selection, resize image etc and other common actions
- Get rid of the "Open" and "Save" text on those buttons, which would free up some more horizontal space
