I'd love to see full 2-way control, not just by title but complete with cover art and media descriptions on the Pronto.

Generating thumbnails and incorporating them into an XCF looks nice, but is a chore to maintain. It would be much better if the Media Center interface generated cover art thumbnails and sent them to the Pronto as folders (My Videos, My Music, etc) are browsed. Media Center automates cover art download and metadata (plot summary, actors, director, cover art) based on the DVD ID of a movie. It would be great if that was extended to the Pronto.
