I dunno if it counts, but I use libreoffice more than anything else. It's a very well made piece of gear.
I've written multiple novels with it, short stories, essays, a home brew ttrpg system, etc. It doesn't just do "good enough", it is on par with anything else I've ever used.
Honestly, I installed it on my windows PC recently, and I found it really clunky. And it sounds like there's no dark mode?
I do IT for a living, and for as big of a bitch Office is, it does work pretty damn good... When it's working. I felt like I went back in time a decade when I was working with Calc.
I'm not trying to fight, but I'm genuinely curious, do you only use Writer? Have you worked with Word lately to compare how they've changed? Thanks
Dark mode is coming to the latest release of LibreOffice, or very soon, so I've heard.
It's possible in current and recent older versions to change the default colours to almost-but-not-quite emulate a dark mode. I have to admit it's not a quick thing to do, nor is it perfect once done, but it can be attempted. (That said, maybe I gave up changing things at "good enough" which is why it's not perfect.).
Oh, I've used it, and it isn't worth the price. They could offer it for free and I still can't say I'd switch. It isn't that there aren't differences, there are. They just aren't enough to matter.
Writer, that's the bread and butter. Calc is mainly for tracking timelines, "lore", etc. Draw isn't a common use.
Dark mode isn't as superior when writing long form though. It's nice, but it's easier to catch weird patterns for me (dyslexia). Calc vs excel, well that's not really a competition for professional use, though calc functions well enough for the kind of use I put it to.
