Timeline Object Ordering and Grouping

I’ve been using the new 0.7.5 update now for a few days and the new UI is a huge step in the right direction. I really like the changes since the last version. The one thing so far that I’ve found can be a bit tricky is keeping track of what item is what in the timeline. If you have a lot of the same node type there is no way (at least that I know of) to distinguish them apart from one another. One idea I had was if you surrounded a group of nodes with a comment all the nodes could be put in some kind of group and be a child of whatever that comment is called. Then in the timeline, the group would be visible and you could open or close the group and it would hide or reveal the contained nodes. It would also be nice to reorder the items in the timeline (I don’t think you can do this currently).
