It would be nice to have an ability to add a caption to an item on complex screens.
For example, there is an ICMP Ping template attached to a lot of hosts. Hosts belong to groups according to their site or location. There is also a complex screen with ping graphs for a router of each site, lets say 100 graphs on a complex screen in total. Graphs are automatically named by Zabbix as "10.20.1.1: Ping Time" or something like this, we don't fill in "DNS name" field on the host configuration page. This caption doesn't say anything about host location, as it's very difficult to remember network addresses of a 100 of sites. So I request a feature to optionally add a line of arbitrary text above a graph or any other item of a complex screen.
