@RoyA very nice work so far.
Your agents successfully move notes forward to a new (longer duration) interval when the review is “correct” – but do you plan to add logic to the agent actions to move notes backward to a shorter duration interval when the review is “incorrect”?
It occurs to me that an Attribute Browser view might be useful when reviewing notes, since Attribute Browser can be used to group your notes according to the $ReviewInterval – e.g.,
This might be more efficient for study sessions than navigating around a series of agents containers.
I’m not sure that $DisplayExpression can include images – I know that images cannot be pasted into $Name. If that doesn’t work, you could use badges.
