It's better than Libre Office. Only the close, minimize buttons should be replaced by the ones for Linux so that they don't not have this Windows look. Please, also fix the interface scaling.
O melhor office que já testei para substituir o MS 365 com arquivos na nuvem MS OneDrive
I was using this on Ubuntu, and it worked really well. I used desktopeditors --force-scale=2 to change the UI to a scale more suitable for HiDPI monitors. However, that doesn't work on LM20 for me, and nor does right clicking on a doc to open in OnlyOffice. Maybe it's because on LM it's the Flatpack version, and on Ubuntu it's the Snap version.
1) Cannot change the look (get rid of that righthand pane) 2) Cannot associate file types. 3) Even when you select a file and right-click "Open With", it opens a blank new file and not the selected file. Did anyone test this before releasing it? Looks pretty though.
This is the best office suite for Linux users. AWESOME!
If you need a lite office package which provides the basics (word processor, spreadsheets, and presentations), Only Office is for you. I love that it is available across multiple platforms, has robust tools, and saves files in all the major formats for compatability. Go for it!
