There is no way to move completed plans off of your hub.
I have some plans that are complete.My choices are to delete it forever or leave it there to clutter my hub. Why not at least have a "Completed Plans" tab on the left, and let me drag completed ones there to refer to if needed.

I love this idea i want a way to look at old plans but I don't want them cluttering up my current views i need an archive folder of old plans so i can keep things clear and clean.
