Dashboard/Timeline

There's a black hole of information in Cortex - a CMS should be very good at telling an administrator what's changing within their realm. We need a ticker/timeline either as a drawer or as a dashboard. Will update with potential gems and mockups.

If we switch to JCR/CMIS/etc, we could make a wonderful contribution to the community by creating a gem/JCR extension (?) that appends a bit of metadata to the base content object: timeline icon, display format, etc.
