I've been looking to replace Google Docs with a self-hosted option, and my choices are essentially LibreOffice and ONLYOFFICE, which both offer in-browser versions. ONLYOFFICE is much more limited, but it's much more user friendly, so I'm definitely leaning that direction. I like the LO project a lot more, but they really need a UX expert to help me make it more approachable.

I'll play with the new LO before making the final decision, but I certainly agree that it has been a pain for some time.
