It is interesting how LibreOffice has grown, yet no matter how much attention it gets (even professional contributions such as from Collabora) it remains buggy, jittery, and with an ugly and non-intuitive UI.
Many bugs are over 10 years old, and it doesn't seem to have any substantial progress in terms of stability, ease of use, or usability. LO development feels more of a 'let's experiment with adding this new feature', rather than a serious product development.
I wish there was a new open-source office suite in development, especially when languages like Rush are now available.
The real issue I suspect is - who needs to create "documents" any more? I use Calc without any issues to do spreadsheet stuff, but have never needed to share one with anyone else. Writer, not for years. People often work on things they want to use, so getting commitment might be getting more difficult.
My question is, assuming you are not a business, what do you use LibreOffice for?
