exactly! The sole purpose of the nit_focus component is to be replaced. :-) With less than 50 lines of code, it showcases the implementation of the policy that was formerly built-in in nitpicker. Since I moved this policy to this external component, we can do anything we want by replacing it. > The layouter should generate a report with the label of the > current window on top of the stack, and this new component generates the > focus report accordingly.

Worth integrating into Genode? It is exactly the direction I want to go. The externalized nit_focus component was just a stepping stone. Still, my remark about the nitpicker-focus handover between sessions holds because such a mechanism is needed regardless of the layouter's / nit_focus policy, e.g., for implementing dialogs with menus or sub-dialogs.
