In general, I also am a LO fan, but recently it left me hanging quite a bit.
I wrote my CV in LO, to avoid my endless tinkering mode, that I had with my LaTeX CV, that still never looked exactly how I wanted it to look. Then 2 things happened:
I upgraded my desktop computer from Debian 12 to 13. Now LO can no longer start. I am only getting a crash without UI error, and on command line I get a nothing saying C++ error, saying "std::alloc bad alloc" or so, and that's it. No details, nothing. Already tried reinstalling a few things, including LO, but apparently it doesn't come with all it needs.
On my laptop, which is the same OS, Debian 13 LO still works, so at least I can edit my CV. However, there is another issue there. Scrolling takes approximately 1s, before the document is re-rendered. I found out I need to set an env var to make LO use XWayland compatibility layer, instead of using Wayland directly, because if it uses Wayland directly, it is just pure laaaag, unbearable scrolling experience.
Needed: Way better error messages, not just slinging low level C++ crap at me.
Needed: Why doesn't it recognize Wayland and perform properly when scrolling?? Or act through XWayland by itself, rather than me having to search for a solution for an hour? If the Wayland experience is that rough, maybe it should not use Wayland at all and use the XWayland instead from the start?
In short, a very bumpy experience recently. But once it works, which it still doesn't on my desktop PC, it is maybe the best word processor tool. Briefly I looked at OnlyOffice, thinking it is also free/libre software and maybe it is good, but alas it is a child's toy, when it comes to editing styles. Character styles don't even work properly, so it's an instant no-go for me.
Maybe I will investigate Calligra, which has been mentioned here.
EDIT: Tried Calligra. Couldn't even open the first fairly trivial odt document I tried: My CV. My CV document is basically just a few tables with text in them, one photo, bullet lists, some paragrah styles for headings and such, and some character styles to highlight words. The writer tool of Calligra instantly crashed, with no error message dialog whatsoever. It does have paragraph styles and character styles, but the font rendering looks weird, blurred as well and often users a way too small font in the styles editor. Aside from paragraph styles and character styles I didn't see any other styles in the styles editor though. What about list styles, table styles, page styles ... To me the writer tool of Calligra looks also very immature at this point. (version 1:25.04.2+dfsg-1, as shown in "Discover" on Debian 13, KDE)
EDIT: Maybe I will truly have to invest more time and create a good looking LaTeX CV. Or just be lazy and use something pre-made I find online. Though I already know there will be something that will not satisfy me or that is not anticipated by some pre-made template and then I will probably be fiddling with it again ...
