Best PowerPoint Plugins

Hello WSO -

I tried searching for this but was unable to find an exact match for my question. My question isn't "what are your favorite PowerPoint shortcuts" but rather what are some of your favorite downloadable PowerPoint plugins? I'm trying to find a few that might improve productivity. Seems like something that should exist. For example, Capital IQ excel plugin is tremendously useful but the PowerPoint Capital IQ plugin is severely limited.

So far the best I have found from Google is "Power-User."

Bonus question, does anyone know how to make a QAT command to fill a specific color? I know I can make a command open up the fill color cycle but I want to press like ctrl + T to fill a shape blue or something along those lines.

Thanks in advance!
