Just installed but got a good impression about the general concept. For myself, I found Timeline looking deliberately for this function (a running visual timeline), but i think that, with some fine-tuning, it could turn into a very popular add-on, it's the kind of thing people don`t usually know they need until it crosses their way.
Some benefit would result, though, from vertical scalability or support for displaying 2 or more concurrent events without one getting on top of each other.
