Thansk for the quick reply.
Yeah i know it's not supported now. But you solved it somehow on the parent tracks, so i was hoping you could do it for the children.
Another feature idea:
An option in tags panel, to treat non tagged tracks as a tag group. That way if i insert a new track or have a non tagged project, i don't have to tag all channels if i want to hide them, or show only tagged ones.
Maybe there could be a special tag dispayed in the list like "NoTag" or something better. (maybe coloured differently to not confuse with actual tags)

So basically it would work like this:
If track has no manual tag, it will be assigned to the NoTag special group.
