Configurable (selectable) icon themes for Office
The Ribbon needs to be configurable. Mine just took an additional half inch of the display. The icons would be great for grade schoolers but I'm an adult and this looks silly.
Provide a collection of themes with reduced icon sizes and a more business like graphic.
Indeed, it is more than required to have choice between colourless and coloured.
For instance, the choice is freely possible in Solidworks.
