Now we have several features (see attached pictures). There is no common prefix for them and that doesn't help to ease update/uninstall. Now they are
scattered between installed items and it is difficult to find them in Installed Software list.

So my proposition is to have prefix JBT or JBoss Tools for all features to keep them together in Installed Software list. Another solution is to have pattern for feature names, for instance, JBoss <component name> Tools, so list would look like:
JBoss ESB Tools
JBoss Seam Tools
JBoss Protlet Tools
JBoss Struts Tools
JBoss ReachFaces Tools
JBoss WS Tools
JBoss Hibernate Console
JBoss AS Tools
e.t.c.
