Timeline Viewer: add "jump to most recent item"-button
I think this would be helpful if you have Timelines with a lot of videos/items. Then you don't have to scroll down all the way down to the most recent/latest item on the Timeline. I guess at the moment this means that all items on the Timeline are loaded, but that's also the case when you scroll down the whole Timeline.
Could be an arrow down icon at the right bottom corner or something like that.
