Update: I have found in the class.search.php comment to "SavedSearch" class: "staff_id - (int) Agent to whom this queue belongs (can be null for public saved searches)" so it looks like public searches are possible. But I couldn't find any way in the UI to save search with null in staff_id. Also, as I can see in phpAdmin 'staff_id' field of <prefix>_queue table is not nullable.Before I'll do my dirty hacks I would like to ask if this feature is already somehow designed and maybe it is on its way to be implemented, so that I could at least make my hacks consistent with future versions of osTicket(or maybe be instead of making own hacks I could develop this feature and contribute it?)
