Speaking of tiny, incremental improvements, Erica Sadun over at TUAW highlight a new addition some developers are seeing when entering iTunes Connect -- a submission history:

Appearing near recently reviewed items, this option opens a detail table showing how your application has worked its way through the App Store review process, and on to the shelf. Stormont details this update on his site.

Sadun also states that the amber status bubbles are slightly more verbose now, adding "waiting for review" for the freshest uploads.

If you're a developer and you're seeing these, or any other changes in iTunes Connect, let us know, and let us know what you think about them, and what else you'd like to see.
