During the tests of the new version this wasn't really an issue, but in the old version it was extremely tedious to find the right Timeline and within some Timelines it was also very hard to find the right video. In the old version I had 90 Timelines (without all the Griddle Sequences) and the Timeline of the process documentation of Effect contained around 70 videos.
