I get that it’s open source provided you use codium not code but I still find that interesting
Microsoft Office suite is obviously superior to its concurrents. If it were available on linux I’d use it, despite being about FOSS ideology. Sometimes, non-FOSS can be better alternatives. However, OnlyOffice is still neat and gets the job done.
Ohh can you do Exel-Style arithmetics in Word tables? You can in LibreOffice. Maybe it’s just so widely used no one really knows other Office programs are basically on par with MS Office or even better.
LibreOffice UI is really… well… old. UX is really bad : it’s on par with GIMP’s ideology of “make it as hard as possible to get things done”
