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?
I once made an animated presentation using Inkscape and an add-on I can’t remember the name of. It was epic and blown everyone’s mind. But it was not worth the effort and I have never attempted this again.
Which elements do you want in it that you can not find ? Only simple transitions like this or I am sure you have specific issue… https://www.youtube.com/watch?v=1WzigWN_c2g
Lately I’ve been using Sent.
https://www.onlyoffice.com/ may be an option. They have hosted plans but you can just use the office suite with local files for free if you don’t need a yof the hosted offerings features
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).
LaTeX with Beamer for slides, and show the resulting PDF on any computer you want
