Why would you want that. You just rightclick on the file and press preview

Yeah, but it has to open your media player specially to play video. It would be much better to have a small screen in the corner of limewire itself.

I still don't understand why you would want that. There are a lot of other features that need to be implemented in Limewire

But OK it's a request

I wonder if thumbnail previews of image files might be feasible for future builds? (a la explorer)

BUt what about a search bookmark option and a completed download notifier in the system tray?
