My biggest wish right now is for the ability to share the usb dongle with Zwift. I just got in the Zwift beta, and they say that they have structured workouts on their road map, but I don't know when that will be. In addition, I would be curious to see if Zwift is using the same power curve algorithms, and it would be really nice to use Peripedal on one monitor while I do zwift on the other for a few workouts to see how the two programs report the power numbers etc.
If sharing the usb dongle with another app is an impossibility (which I suspect it may be with the nature of the drivers etc), then I would still find it useful to have Peripedal able to basically just run in a timer mode. Essentially have it let me tell it when to start, and then have it display things as if it is progressing through the workout. That would give me a means to run the peripedal workouts while using Zwift as well. Zwift does add some fun/interest to trainer rides, so I would love to be able to get the best of Peripedal with the fun of Zwift.
