We should list the accepted tasks somewhere but maybe this can wait until after part 2.

"selected" and "selected_order" are redundant in some cases - I think this would be better if selected_order is negative if this task is not selected, and non-negative otherwise.

Apart from that, maybe this should be documented. It is unusual (to me) that a selection can override something being enabled, but that is the case here.
