It would be helpful to be able to scroll right past the end of recorded content in the Keyframe Editor. For instance, if I want to click and drag the last track to make it longer. The only way to do this is to zoom out on the time-frame scale. If you press the "scroll-right" chevron > the nothing happens. This would be a small feature but would improve the animation editing experience. Most programs have this functionality (Excel for instance).
