> Most people also like that LibreOffice looks like what Word and Excel looked like before Microsoft changed up the menu system.

I feel exactly the same way about that. And I often use it for stuff I don't need to collaborate on. But for paid jobs with stuff I need to round-trip with people who I know are using Microsoft products, I just use the Microsoft products myself.

It's cheap insurance against giving the people who are paying me to collaborate with them a bad experience.
