-Name outlet for vst. Can be done with IML but a name outlet for vst factory (and caption) name would be useful.
-Vst ID. Would be nice if each vst could output an unique (short) ID to assist in advanced parameters interfacing, especially useful in the case of more than one of the same vst in a patch / workspace.
-Probably a long shot, but if receiving a parameter value could block output of that parameter to array outlet and if controlling a parameter from the vst UI could block input of that parameter. Sort of an internal stop if changed. Would really help with managing feedback loop issues when looping params arrays to and from the vst.
-- lots more suggestions to make vst interfacing even more robust in HH, but this is all probably already well enough discussed in the forums
