I do apologise if this has been covered before. I did do some searching on this section of the forum and to no avail.
My setup, Kindle 3 and Windows 7
My idea for a plugin is that on downloading from your device, that it would be possible to execute a batch file (or command line application) on the copy of the file you just downloaded.
I'm think with reference to this http://code.google.com/p/kindle-annotations/wiki/Usage
I'm a bit sad to see the annotations I do on my kindle don't copy over. However using the above applicaiton I have been able to produce a pdf with the annotations included.
While running the command manually isn't impossible it would be great if the above idea could be implemented.
