Many users keeps falling into our trap of thinking that the "All JBoss Tools" contains everything when it does not.
The word Abridged would keep it still at the top and actually mean what it means: "not full, but reduced set of stuff"
And the category description should be changed too to not show as the only line (default visible):
"Contains ALL the plugins that are available from"
to something like:
"An abridged selection of JBoss Tools plugins"
Nick, placed on M4 in case its a trivial site.xml editing job - otherwise move it off to just be done in trunk/beta1.
