The developers of Ara posted a new update on Steam, writing about the next patch, which is scheduled for June 18. They plan to address 6 points in total, among them UI, AI, map generation and more.
In this update they specifically write about the UI, and that they plan to make all interactions possible via the main map, in contrast to e.g. the city screen.
