@ikey, my engineering internship this summer will use OnlyOffice as online office collaboration tools. It provides the best compatibility with MS documents of any editor out there, especially compared to LibreOffice, and definitely so when dealing with graphs and lots of scientific data. I currently have it installed as a snap, but I am getting odd font issues and I'd like the option to install it from Solus SC natively. The editors themselves are open source: here is the github page. Thanks for your consideration.
