I am not happy with the actual change to give the reintroduced timeline the quick navigation buttons from dope sheet, graph editor etc. . It is visual noise, and makes no sense, workflow wise. The timeline was never meant to be part of the animation editors to actually edit the animation. It never was in the past. It provides the play elements.
It is also troubled implemented anyways. It shows that you are in dope sheet and in timeline. If even then these elements should be grouped together, to actually have five buttons, and not four plus one, with inconsistent display and behaviour. Which button shall the user click here?
But as told, when it's about me then remove the quick navigation buttons from the timeline all together. When you need the Playback controls, then turn them on in dope sheet or the other three editors. You can show them as a footer there.
