Google announce users can connect Drive-enabled Chrome apps. The Google Drive Create menu now elevates Drive-connected apps to the same level as Google apps such as Docs and Sheets. This makes your Drive-connected apps easier to reach and more visible to Google Drive users.
If your app is already Google Drive-enabled and listed in the Chrome Web Store’s Drive collection, you don’t have to do anything new to take advantage of these new features. We will automatically pull all the information from your existing Chrome Web Store listing.
If your web app is not yet Google Drive-enabled, check out how you can integrate with the create-new and the open-with actions and then get your Drive-enabled app listed in the new Connect apps to Drive dialog.
