Smooth migration from screens to dashboards requires some changes. Existing screen element "Screen" cannot be migrated to Dashboards, it should be removed.
- Existing screen element "Screen" must not be supported anymore
- A database patch must be created to remove it from all existing screens
- Documentation must be updated
- I want to have only dashboards that should incorporate most of functionality of screens
- There will be no support of the "Screen" element in Dashboards. It is a functional regression, which will hopefully affect only a tiny fraction of Zabbix users.
