Ich bin zwar kein großer Freund der Aufsplittung der Dokumente in Drive (und bei den Apps) nach Dokument-Typ, aber die Übersichten sind auf jeden Fall hilfreich!
Home screens for Docs, Sheets, and Slides are officially here!

Now when you visit www.google.com/docs, www.google.com/sheets, or www.google.com/slides, you'll find an easy way to get back to your most relevant and recently edited documents, spreadsheets, and presentations.

And don't forget: you can quickly create something new with a click on the + button, edit Office files by installing the new Chrome extension (http://goo.gl/yHbngd), and once you enable offline editing, everything on your home screen is editable even when you’re not connected to the Internet.
