Submitting bugs and enhancement requests to Google Documents webapp

Question

Question

Does Google provide a public bug tracking system, issue tracking system, or enhancement tracking system (similar to, say, Bugzilla) into which their users could submit reports to actual Google developers and not just other users (note: see below the Dead-End Reference Material that specifically excludes Googles support forums)?

The following are links to my web sleuthing that turned out to not be answers to this question:

1. Note that I already know about the various Google-app-specific Google support forums (e.g. http://webapps.stackexchange.com/a/2583/14529), and that is not the answer I am looking for.
2. Google search: how to submit bug requests to google documents
3. Is there any where to submit feature requests for Gmail (or other Google apps)?
4. http://webapps.stackexchange.com/a/35171/14529
5. Report Gmail Bug

Answer 1

No, there's no public bug tracking system for those Google products. Sometimes Google employees participate in discussions in forums, like here: http://productforums.google.com/forum/#!topic/docs/2E9tLNWdhAw

Note that Google Employees have the small Google icon next to their name.

If you are a Google Apps for Business customer, you might be eligible for contacting Google support via phone or email: http://contact.googleapps.com/?&rd=1
