When i zoom in on the timeline it usually zooms with the playhead in the middle. However, when i am in the effect control tab the zoom starts to act abnormally. When zooming close to the maximum limit, it starts to zoom in an entirely different place than the playhead.
If i'm for instance zooming in on two keyframes that are close together, it becomes very hard to find them again, when zoom is zooming an entirely different place in the timeline.
I hope that made sense. If it didn't, check out the video.
