As a sheet author, I would like to be able to have Inputs / Attributes that can be set from the Worker scripts or included in Roll Templates but are not saved as a Character Attribute and are not propagated to all Players viewing the sheet. Such attributes can be used for: Navigation. (Currently, using attributes for sheet navigation causes the navigation updates for all players viewing the sheet.) Making selections for a "dice roller" control, such as the one in the Chronicles of Darkness sheet. There's also the somewhat minor benefit of these attributes not cluttering the list of Character Attributes.
