The Amazon Kindle app is a pretty important app to have on the platform, but according to the reviews are not that much loved, with many issues related to bugginess and lack of features needing to be addressed.
Amazon has finally made some move towards this, and have updated the app today to version 1.2. The update brings support for fast app switching in Mango, and also allows individual books to be pinned to the start screen.
Unfortunately numerous other features, such as being able to highlight passages and crashes remain, suggesting Amazon still have quite a bit of work to do.
The app can be found in Marketplace here.
Thanks Jeremy for the tip.
