I'm a coach with a large (50 person) team, all following the same basic periodization scheme for their year. It would be amazing if either (or both!) of the following capabilities existed:
1. Ability for a coach to copy & paste a "basic" annual training plan from athlete to athlete. I can apply a weekly plan to multiple athletes, but I can't do the same for the ATP - I have to build it from scratch for every athlete.
2. Ability to see an "ATP View" for a training plan that I load into an athlete. For example, if you could compare the "training plan ATP" to the "athlete ATP" you could see how that athlete's plan was set up to deviate from the group.

These are things that don't matter much for day-to-day programming but make a big difference in athletes understanding the "why" behind the "what." And, honestly, this makes me rethink using Training Peaks for my team.
