Thanks!
Since foreman_column_view has been sunset now, let me come back to this idea: Would one of the UI/UX devs be interested to add a way to add a custom card, showing custom facts?
With this, I think we’d have full feature parity to the old host details page (and of course more features in addition). As it is now, there is no replacement for foreman_column_view for the new host detail page, i.e. no way to add custom facts which may be site-specific (such as the programmed rtcwake time which is of interest for us, but not of general interest).
