Personally, I would like it even better, when you could select multiple movies and rescrape them (actually update the info).
New films sometimes have no info at all on IMDB, after a couple of weeks IMDB updates them, so I would like to rescrape my movies time to time (without losing my selected fanart and thumbmail).
If you make multiselect possible in the left box and let the first selected be the displayed movie, you could do things like:
Remove info from selected movies
Update (Re-Scrape) selected movies
Output selected movies to HTML
I like the way you scan folders now, would be nice in the other options, like the "scan for new fanart" also.
Looking forward to your update.
