I am using libreoffice in science and I would like to say that I really like it. However, there is a bit of suffering during collaboration with Microsoft Word users. I might be in the wrong place but as future feature to add is the track changes in the ballon rather than in the middle of the text. In fact, after few document revisions it is hard to visualise the final manuscript in all its part. Toggling changes it happens that pictures gets misplaced and so on.
The track changes on a side of the document would be a really great benefit for all.
