Ability to create folders in training plans
This would be similar to how you can create folders for workouts. If you have many training plans across different disciplines is can be quite tedious to find the one you're looking for. With the addition of folders, you could group them by season or discipline and make it much easier to find what you're looking for.

It would be wonderful to be able to sort the training plans I’ve purchased into folders. I’ve purchased some plans that I don’t like, others I’ve loved. I’d like to be able to put them into folders (and/or hide some) so that I know which ones I would like to use again, and which ones I don’t want to see anymore.
