One thought/idea: would it be possible to have parent visibility toggles (or something like them) work on tables in CODAP too, in addition to graphs? (also what about maps? I thought they worked on maps but apparently not). It strikes me that this these toggles are kind of like the check boxes you can use for filtering a table in Excel (and consult later to see exactly what you are/are not seeing in the table). If there were parent visibility toggles (or something like them) for tables in CODAP, it would be pretty quick/easy to determine what has been filtered out.
