Please let there be Media Delete capability for Roku clients, soon. It's the only thing missing for the wife and I. It's incredible without this feature, but would be even BETTER than sliced bread with it!
Sorry, but as far as I'm aware, this isn't in anyone's plans to work on. I know it's not on mine. I think the consensus is to keep admin functions on the web client and let the Roku client simply be a user client.
