I always expect to be able to right click a part and get the edit option. Putting it in the timeline is good but I find there is a real disconnect between the items in the time vs browser vs the actual part. I think this highlights a bigger issue in the interface paradigm but for now just give me edit when I right click a part! Since parts in the timeline arn't named I have to memorize where the part is just so I can go back and edit it.
