Huh, I guess $TimelineBand is an intrinsic attribute.
In that case, @jxxmxxj, setting it in the prototype won't work, since intrinsic attributes (such as $Width, $Container, and $TimelineBand, evidently) are not inherited from prototypes. Easiest would probably be to set it with an Edict in the prototype. I.e., add this Edict to the "Learning goal" and "Standard" prototypes:
$TimelineBand=2 to the Edicts of the "Activity", "Assessment", "Resource", and "Problem" prototypes.
Or you could use an agent, but if you do use an agent, make sure that you specify that you wish to set the timeline band in the original note, like this:
$TimelineBand(original) = 1
otherwise you will only set the timeline band of the alias (since aliases do not share intrinsic attributes with their original notes).
