How to reduce the size of quick access toolbar icons? (Office 2016)

if you move the QAT below the ribbon it displays in color.

Cool.  It kinda works.  It does work in White and Colorful, but not Dark Grey (in Word 2016, not 365).

So "color" works in 2016. Now they just have to fix it in the places it is not working !

Folks, our shared UX controls team have been following this thread, as well as your requests on UserVoice and are spinning up some work to address your concerns. I can't promise a specific date for getting this work out to you all, but they recognize the impact this has had on those of you who work with customized QAT and are moving very quickly.

When they're done you'll see the improvement arrive as part of the regular updates we send all subscription customers.

Thanks again for the clear feedback, both here and on UserVoice - keep it coming!

OK, it's now July 4, 9 months later, Do you have fix for these jumbo icons?  They appear to be  40% larger than in office 2010

I can't fit all that I need AND ONCE HAD across my screen.

The borderless interface is horrible - there should be an option to skin it myself and show the entire button or icon area with a background shade ( think for selection purposes - that's what us users do), even better would be something like light and dark gray between button (that would show all the wasted space you have allocated).  You could continue the light blue highlight of selected items (for contrast)

looking forward to a resolution and reply.

It's been a year, is there an option for smaller QAT icons yet?
