I'm not sure why this isn't the default, but if there is a good technical reason to not always replicate templates, you could make it where a template could be marked as "distributed". That way only "distributable" templates replicated to the child nodes?

I strongly agree - syncing templates between nodes would be very helpful in the following situations:

• copy templates from zabbix test environments to productive environments
• copy from master setup to the distributed nodes of our customers
• copy templates from distributed nodes to master setup

A mass operation in "Configuration" => "Templates" would be useful.

Please? +1

Very very necessary feature.

Feature ideas:

• manual sync (only on parent node):
  • open configuration => templates => <template-name>
  • press button "clone to node"
  • select a node
  • template on node will be completely replaced by the template of the parent node (no merging)
• permanent sync (only on parent node)
  • open configuration => templates => <template-name>
  • setting "permanent template synchonisation"
    • select nodes for replication
    • the template cannot be change in the child nodes anymore

• check sync
  • open configuration => templates => <template-name>
  • show sync status of all sub nodes

with nodes removed in 2.4, this one is unlikely to be looked in
