I appreciate the response! I can say for sure that all four of our staff that prototypes on a regular basis misses having the bold setting in the toolbar greatly. Underline is probably the next most used formatting that we would like to see added to a toolbar menu. Changing weights is done so often in our prototyping workflow that drilling down into the inspector impacts our efficiency in prototyping.
