Better keyframe pane controls for the playhead

When I’m making changes with keyframes, the horizontal scolling of the keyframes timeline in the effect properties window doesn’t move or scroll whenever i play the video or click around in the video timeline. I waste a lot of time navigating this pane to find the playhead or the areas around where I’m working. This includes having to zoom out and in on the timeline and manually search left and right for the current play point. 

Please add:

• A toggle to follow and match the position on the timeline
• A toggle to stay centered on the playhead
• A button on the top left and right of the timescale to jump straight to the playhead
• A toggle that makes the zoom level of the keyframes timeline match the zoom level of the timeline
• A way to quickly delete all keyframes for an effect after the current frame (to save having to zoom in and select all on screen after the current frame, making sure to not miss any tucked up close to the current frame, and then out again when you’re done)
