Save space with a Microsoft Office app?
I've noticed that each of the apps for Word, Excel, and PowerPoint are quite large. They are also independent.
I'm not sure if this would lead to any improvement, but perhaps we could have a Microsoft Office app. Then get the individual components of Microsoft Office through in-app downloads. This way, any features that are common between the components can now be shared in this single app, which should save space.

That makes it worse actually. It is why Facebook split out messenger. The code got so nasty it was difficult to update in one MASSIVE app.
Google split out its Google Apps a few years ago too for this very reason into the spreadsheet, documents, etc. apps. Easier to keep stable.
