I tried moving a top level group inside another group. Syncing this makes the group show up as nested in dttg but it also remains at the top level, because its a sync group. Ugh, I’m not sure if the current way of syncing is going to work well in the long run. Having to separately maintain sync groups if one does a lot of grouping and regrouping is going to be a pain. Maybe the iTunes method, of checkboxes next to each item would work. I’m might not like the additional UI clutter for that but that’d work if it were also hidable and available in an inspector.
