Application indicator support for Zeitgeist

Zeitgeist can be used to track activities/files and relations between them (in a "most used with" fashion). An application indicator could display the most used activities with the one you have focus on.

A few days ago, I worked on A, B and C. If I open B, the app indicator menu gives me a way to quickly access A, C and others things I didn't think about, like the name of the person I was chating with on Empathy while working on B, or a wikipedia page I use to check while working on this project.
This will bring light, intuitive and immediate access to useful elements directly related to what I am doing right now.
