Why is there an option to focus on the datasource or instance level?

@Stuart Weenig - it feels like the YUI (V1 UI) to V2 UI all over again!

Here’s how it will go down:

1. LM: This is great! Use it!
2. US: Er… no.  This needs a complete rethink.
3. LM: How about now?
4. US: You’re not listening.  There is basic functionality missing.
5. LM: We’re going to force you to make the change.  We’re switching off the old UI in 2 months
6. US: No you won’t.  You value customer retention too much.
7. LM (2 years later): How about now?
8. US: You’re getting there (users actually prefer the new UI)
9. LM: Right, we mean it this time.  We’re switching the old one off in 2 months.
10. US: Whatever
11. HIGH VALUE CUSTOMER: NO.
12. LM (2 years later): It’s done.
