Please add the navigation buttons to the graph editor and dope sheet

I never understood why in Blender there are the navigation buttons to go to the start and end of the scene, previous and next keyframe, and play forward and reverse, but only in the timeline area and not in the dope sheet or the graph editor. When doing any work in those two, I find myself needing those buttons, and while there's plenty of space for them, they are absent from those views.

The workaround is to setup a timeline area and shrink it down to just the buttons, but that becomes a pain when you have to move the divider between the lower area and the bottom area up and down depending on which one you need more space at a specific time.

In fact, these navigation buttons could also have additional buttons for markers, because keyframes only show depending on the object selected, but markers are scene wide, and there may be important frames in a scene where it would be useful to just click a next marker button than scroll to it.

But it would be great if at least we could have those buttons, and the auto keying button in the toolbar of both graph editor and dope sheet.
