I've also found a service code named "people" (not peoplesense). Is it new?

Yes, I believe it is. I'm obviously slacking off a bit with my digging... :-)

With a Mail Merge-like function (see http://support.microsoft.com/kb/294683). A nice way to integrate Gmail, Docs and Spreadsheet (and App Scripts) together.

By the way, Ionut, do you have any idea about this icon in Document?

I've also found few unkown features:
* cloudboard (I think it's related to the icon shown above, see http://cloudboard.codeplex.com – would be link to Cosmo, hence the feature called "cloudboard_NATIVE_integration").
*powerkey
*modular_editor_js
*comments
*document_translation
*shelly_chrome

It's the online clipboard.

You can now share folders in Docs, at least via the API:
<<To share a folder, simply provide a folder resource ID instead of a document ID. This example grants everyone on the domain example.com the ability to read the folder's content>> http://code.google.com/apis/documents/docs/3.0/developers_guide_protocol.html#ACLSharingFolders
