As someone who loves statistics, having access to Total Time Watched for each channel would be really cool. I could use it to sort channels my family watches the most towards the top of the list.
One of the things I kinda miss from Tivimate is the ability to "Sort Channels by: Watch Time". I would occasionally turn it on, just to see how the list changed. Maybe Channels DVR doesn't quite need that specific feature, but getting the Time Watched information could be useful for those of us who are curious.
Even better, if that info was displayed in a list somewhere on the browser dashboard/settings.
