Reduce the space taken by header

On this and many other screens the heading, which consists of the title, type of the view "Starter roadmap", switcher for "Milestones|Epics" and view control buttons, takes the hieight of at least 3 rows of content below (e.g. 3 epic bars). Having it reduce to 1 bar would mean that 2 more bars of content can be shown below and less scrolling would be required.
