LibreOffice 7 on my workstation

I've just noticed I could full-upgrade to LibreOffice 7 on Debian unstable.

It's a new world to explore. I'd like to study some Python 3 scripting. If we could replace the obsolete and proprietary VBA macros in MS Office documents, it's a major contribution to document freedom (and software freedom). Also, there should be something new to replace the StarBasic macros in ODF documents, and Python 3 sounds good.
