There is an outline view on LO
Also Exchange my be corporate must have, but it and Sharepoint are horrible.
Google's Web mail.
Why all this space on Wordperfect, MS, Google on an LO article?
Also there comes a time when new feature are stupid and getting rid of bugs is more important. Compared to 6.x the 7.4 floating / undocked tool windows don't work, but outlining works better as your position is tracked in the Tool Window. You can even right-click and export Outline to Clipboard.
The idea that Online will replace a local Wordprocessor is bonkers. One is your own computer with your own backups and doesn't need the Internet. Online/cloud is someone else's server. Only makes sense for real time collaboration, Social Media, online ordering, forums, websites etc. Not content creation ever. That's 1960s terminals on rented server time.
This article tells me very little about LO 7.6. Which presumably runs on Mac, Windows, Linux. But which cpus? What bugs are fixed. We don't care about new features.
