So I have a problem. I have already backed the project, but I wish to add some addons. However, I cannot in the world find where or how to access the list of available addons to figure out how much to add to the pledge. The list of addons was only viewable on initial backing, and not viewable/findable when editing the current pledge. It would seem silly if I have to cancel the pledge and then repledge to see the available addons, The project campaign description also does not describe them.
