Some people want to share filters in the old way, such that the sharees automatically see that filter in their filter list.
We have many business users and they seem incapable of doing Manage Filters, Search, entering some params, then clicking the grey stars.
Prior to the upgrade we did have problems with filter and dashboard spam, where people were sharing with too wide a group, so this is an improvement. However in some circumstances we want to share a dashboard/filter and auto-favourite it for the sharees.
Not sure how this would be implemented, eg allow everyone to do this, or just project admins, or add some new permission, or whatever.
