Support ligatures in PowerPoint for macOS
Just like Keynote or Word does it, ligatures such as "Fi" of "Ff" should be automatically formatted by PowerPoint on the Mac. Pretty much every font supports them. This being 21st century, text—especially in headings—looks unprofessional without ligatures.
If this is ever implemented, there MUST be an option to turn off ligatures, definitely not a blanket 'ON' setting, as they are not desired or appropriate in every situation. For one example, text set in a serif font can look better with ligatures, but many sans serif fonts look worse and designers frequently turn them off. This is a very nuanced typographical preference and designers would be mightily upset if ligatures were always forced on.
