At some point (many moons ago), there was a senior architect at M$ who envisioned a blank slate interface with totally customisable menu options and button bars in ribbons that could be context sensitive. It was visionary.
Unfortunately, the implementation was not. The implementation of the function points in VBA was a mess, and the context sensitivity of the ribbon (which should have been strongly event driven) was botched.
And now, 40 years into the game, Microsoft still can't make a settings/configuration page/form for a damn.
It could have been beautiful. Instead, its horrible.
We switched to LibreOffice years ago, and have never looked back. Every further iteration of M$ Office, 365 and their Onedrive abomination confirms that it was the right choice.
