All these clicks are for ploughing through the 'Backstage' view giving you various roads for recent documents, favourites, OneDrive etc, despite the fact that most of these things are already addressed by the native open file dialog. (And turning off the 'Backstage' view in the options doesn't actually turn it off for mouse users, only for the Ctrl-O keyboard shortcut.)
After the complaints in the LibreOffice thread the other day about its 'old'-looking menus it was a reminder that modern Microsoft UI is generally a hot mess that I'm happy for them not to rush into.
You don't even need to actually know the commands to get started with Latex in academia, it's typically fine to download the journal or conference template and fill in the text. All the PhD students I have worked with learned it just fine and fast.
But I still use Word, because odds are good that for any given paper I'll hit at least one collaborator/editor/proofreader/etc who doesn't know how to use Latex, and so using the lowest common denominator (word) saves us all a lot of complication.
Word just doesn’t do double columns very well, and such a niche use case doesn’t seem to be a priority for Microsoft.
