It seems like the update for the Kindle for PC app has gone unnoticed, I can't find a thread on this. Have I just been asleep for a day?
Amazon announced 4/30/2010 that an update for Kindle for PC is available. It includes:
* Full screen reading
* Background color and brightness controls
* The ability to create and edit notes and highlights in your books
They also have a Future Improvements page that lists upcoming features that they are 'thinking' about
:
* Search
* Two page reading mode
* Zoom and rotate images
* Collections
The newly added features for Kindle for PC will soon be available for the Mac as well.
