Google Drive allows you to view your documents as thumbnail images or in a text list. The icon is in the toolbar to the left of the AZ icon. To switch from tile view to list view the icon resembles the list view of lines of text. To switch from list view to tile view the icon looks like 4 tiles.
Tile View
Tile view is particularly helpful when your folder contains images. 
List View
Clicking on the icon in the toolbar toggles from tile view to list view. 
V key
Striking the V key will toggle between tile view and list view. No toolbar icon needed!
While in list view strike the Q key twice to expand the width between the list items.
