If you're talking about the Android email app, there actually is a fork, called K-9, and it's significantly better.

No, I'm referring to the Google Gmail app. Although Google owns Android, there is a large distinction between the open-source Android base and the closed-source Google apps. K9 sounds like a fine improvement over the stock email app, and an example of what would happen if Google would release the Gmail app as open-source. Yet they choose not to --- why?

So people can't get the functionality without Google being able to data-mine.
