I gave LibreOffice an honest try - thinking that “I’ll tolerate a few warts, invest in my tools - especially open source”. I used it for 10 minutes, and decided to uninstall it. While editing a document, I got weird rendering errors, interface was jankt, things felt quite broken. I’m on a recent computer, with minimal special modifications- so who knows what the issues were, but didn’t leave a great first impression.
I’m currently using Apple Pages as my “local document editor” (eg for things to be printed), its fine - but doesn’t handle the “edit this HTML file cleanly” mission.
