New design is not flexible enough.

My previous rating was 4 of 5. The UI is a step in the right direction but it makes too many assumptions.

1. HTTP Body is only available for sites with Basic auth, why?
2. The parameter manager is only available for sites with OAuth, why?

Suggestions:
1. Move the oauth "manage" as the content of the OAuth tab.
2. Make tabs in the top left section. e.g., Header, Body, Parameters
3. Move Body and Parameters into the top left.
4. Rename Basic to HTTP auth. Add digest support if not already available.
