Dear MobilityWOD team,

The scroll bar is only able to hold a certain number of episodes so it has the most recent episodes.
You can add any of the daily rx any episodes for that matter (your goat ones) to your favorites list and they are all in one place.
Granted its not a scroll bar, but it is essentially the same thing as it shows the episodes that you add to it. A greatest hits is another way of looking at it.
All of the Daily Rx are available from the Daily Rx tab under episodes.

Right, it would cool if they could play continuously one after another.  Because many times I am contracting and relaxing far away and 5 mins in and the daily RX is over.  I’d like to have something else on while I am in the movement.
