Con No good video editing for presentations
Con Track Changes needs to be improved
Collaborating on a single document is difficult. Track Changes makes the document hard to read as both edited and deleted text is displayed, it's not possible to print comments, tracked differences between document versions are sub-optimal and there's no system for accepting/rejecting changes.
Con Libreoffice base requires Java
If you need to use Base, it requires Java.
Con Looks old
Con Documentation is out of date
Good luck turning off autocorrect, because the place that the documentation says that option is doesn't exist.
