We are using zabbix maps extensively, both for traditional monitoring and to augment documentation.  For example, rather than having a static document explaining a process, whereby one or more servers, databases, applications interact to achieve an outcome, we are using zabbix to map those processes such that some elements can have live status info.

As a result, our list of maps is growing to the point of being unwieldy.  We've just started and we have 72 maps.  Maps consist of Site/Subnet maps, Application maps, Equipment overview maps(UPS/Physical Server/Wireless Topology) and global overview maps.

It would be helpful to have some sort of filtering grouping mechanism.  This would either be a dedicated "Map Group", or could possibly be served just as well by tying into the host group framework.
