I moved away from MS Windows a long while back and have ported everything EXCEPT presentations. I still use a friend’s laptop just for PowerPoint.
I have used LibreOffice Impress and it is quite poor in design and the templates are very unprofessional.
I have used LaTeX beamer a lot and I am now tired of fighting it to make simple transitions look good, quickly customise a slide, etc.
Are there alternatives that I can use which are libre friendly as well as user-friendly?
Marp works well if you like Markdown. I cannot, however, speak to things such as transitions (though marp exports to a nice HTML file which includes a PowerPoint-like interface, so I’d imagine it’s possible).
Another option using Markdown: Slidev
