The critical point is collaboration on a document. I wish LO had this. You know, like other collaborative editors online, where you can see the other person's cursor and inputs live and all that, with a conflict free data structure driving it all. LO needs this, if it ever wants to replace MS Word in businesses. Even if it would be totally fine for most situations to edit sequentially, there are those cases, when multiple cooks are trying to change a company document, and now they can't, and need to be in a call, to organize their editing or share their writing ideas, because the tool doesn't allow them to edit at the same time.
It does not even have to be in a web UI or browser. Just somehow make it possible to easily connect and edit collaboratively. I know, I know, it is a huge ask, unfortunately.
>It does not even have to be in a web UI or browser
LibreOffice Writer online was not popular, so it is understandable you assume it doesn't exist. There is also the trivial headless Linux remote desktop cloud hosting with 100% identical functionality.
>"edit at the same time"
Perhaps you meant: "View -> Toolbars -> Track Changes..."
Most documents that support OLE have difficulty handling concurrent writes. Office 365 abandoned desktop publishing in 2019, and replaced it with a web document management system.
Best workaround is every user imports each instanced changes: "File -> Merge Document."
And manually handle any collisions.
I would post how to setup your own remote collaborative environment on an $8/month host, but people seem like they are not interested. =3
