- Offline working
- Font changing
- Programmability, and accuracy
- Backward compatibility
I mean, Windows 10 doesn't make it easy to install a real desktop app, redirecting to the web version; if I don't search hard enough (which is Office 2019, for local version).
Makes me really want to migrate to LibreOffice, where I know what I am doing. (And of course, backward compat is ensured, although not perfect.)
