I have looked at the Controllers window for several plug-ins. They do not list many of the controls. Here are a few examples, selected at random.

How do I get the other controls to show up in the window?
---------------
Grr - I just did some more experimenting:
-- select an item in the list
-- click the named title bar on the right-hand side
-- select the desired parameter there and click [OK]
Then it will appear in the list.
Can the context Help be enhanced to explain this?
I think that it would be better if the list on the left-hand side contained the different parameters (or, at least, up to the 32 most-likely ones) to begin with.
