For my sins I have attached a backup drive to my pogoplug, it has over 60 thousand 256x256 images on it (custom overlay tiles for google maps if you must know). It would be good to be able to exclude a directory from thumbnail generation without affecting thhe other directories.

A mechanism to do movie transcoding on a powerful PC would be nice.

And finally the ability to "autodetect" videos that are already suitable for streaming without needing transcoding.
