That's a pretty good demonstration of some of the strengths of the ribbon interface.

After watching this, I went to Google Docs to try to reproduce some of this and it felt very clunky. The first thing I realized I didn't have is a styles manager but I was able to install an add-on. For other parts (like creating tables) I was stuck.

I wonder if a similar demo in Libre Office would be as impressive?

Edit: I just tried Excel Online and it worked surprisingly well. Last time I tried it, Google Sheets felt way better but now I'm not so sure.
