I've tried so many times to switch to LibreOffice, but as far as I can tell it's just not made for novelists. It regularly shits itself when dealing with a 300k manuscript that Word has never given me problems with.
I genuinely tried using it for a full year, using it on Linux even, to see if it was just me being cranky about changes to my writing routine...and maybe it's still just me, but I eventually went back to Windows and my old copy of Microsoft Word 2010.
As far as I can tell, using Libre Office (or Open Office) as an actual writer seems to be a niche enough use case that developers don't fix some of the issues that crop up that are specific to the needs of a novelist. It also gets laggy and unreliable for long word counts.
But if you need to make a basic sign to be printed out, or letters, or use it for short things like so many people use Word for in an office setting, it probably is ok.
I just had trouble with it behaving poorly with my long-format works in ways that MS Word never crapped out on me for.
Dairy has that effect on me. It's not as nice as it sounds. You strain and it comes out with blood.
I was a full grown adult before I learned maybe I'm allergic to dairy protein, after I was poor and went without milk or cheese for two weeks and for the first time in my life I didn't have painful rabbit poo.
