Make Ribbon tabs space efficient - Collapse 'Tell me what you want to do' for narrow windows
The 'Tell me what you want to do" label (along with the Share and Comments buttons) takes up so much horizontal space that it hides most Ribbon tabs when the window is a narrow size. Understanding that not all spreadsheets are displayed full-screen all the time, it would be great if this label collapsed down to something much smaller when the window size is narrow. (Other ribbon controls could also be made more useable for narrow windows by following the lead of how Windows Excel displays its ribbon controls on narrow windows).
Here's a screenshot of Windows Excel with the same sized window (notice how much more functional the Ribbon is and how many more commands are visible):
