Email app that shows your email as threaded conversations?

[tbontb]

The web site GMail.com shows your email as threaded conversations - when it shows "Hi from Joe" it allows me to look at the most recent message or easily look at the whole message chain. I can delete the whole message chain with one click. Does the Kindle Fire HD have anything like that - I cannot find a Gmail app in the Kindle Fire Store. Using the browser and gmail.com is just not as easy to use as a native app.

Between this, not finding an app to play music fetched from my PC via WiFi (separate posting), and the stupid "main menu" user interface, the Fire has been a big disappointment.

Thanks!
