An article by Blair Hanley Frank in PCWorld. Highlights include:
“When users are browsing files that are shared with them but not mirrored in their Google Drive account, they’ll see an ‘Add to Drive’ button. Files already stored in their account will have a ‘move’ icon.”
“Another new icon will let people take the files they’re previewing and add them to their Drive, which is useful for doing things like filing away content shared through a Google Hangout.”
“[I]f users have to search for something in their Google Drive account, they’ll be able to then drag what they find into a folder. That will save them another search the next time.”
