In the past, we decided we did not want all the news posted on the subsites to be indiscriminately displayed on the front page. That's why we have the "Show in Main News" option in the Promote settings tab and news of subsites are by default not promoted to the front page. A nice-to-have and useful addition (given thatthe news feature will be adopted by the users) would be a toggle in https://intranet.molgen.mpg.de/en/news/ where users could unhide the news items from all the subsites. Then, we'd also need some kind of indicator where the respective news items come from (e.g. an additional field with the name of the parent page next to the date or below the title, e.g. "Sequencing", "Works Council", or similar).
