With Composer 2.0 a lot of icons that where shown directly with the old Composer are now collected under the three dot menu.
Since users weigh the icons/functionalites differently, it would be good if you could determine the arrangement yourself. In other words, which icon or which function is accessible with one click in the Composer view and which functions are grouped together in the three dot menu.
We don't have immediate plans for this, but we'll keep in mind as we prioritize future enhancements.
