Resource names often include redundant information. 

e.g.  
JBossAS Servers/host/EJB3 Entity Tree Caches
/EJB3 Entity Tree Cache
//EJB3 Entity Tree Cache Interceptors
///EJB3 Entity Tree Cache Interceptor


e.g. 
JBossAs Servers/host
/Alert Subsystem
/Communications Subsystem

could simply be

JBossAS Servers/Host/Subsystems
/Alerts
/Communications

This example has two problems – 1) Are they subsystems or services? The icon indicates a service, the name a subsystem.  2) Subsystem seems redundant, whether grouped in a 'subsystem' folder or at their current branch.

e.g. 
/Tomcat Servers
//Tomcat(8080)
///Tomcat Connectors
///Tomcat Server JVM
///Tomcat Virtual Hosts
///User Database

could be:

/Tomcat Servers
//Tomcat(8080)
///Connectors
///JVM
///Virtual Hosts
///User Database

This is also an example of naming inconsistency within and across plugins.  'User Database' vs. 'Tomcat foo' and 'Tomcat JVM' vs. 'JVM' in the AS server plugin.
