toolbar, dockable, and actions

I have several questions related to assistants, toolbars, and actions.

1)  I've figured out how to create a toolbar and also a dockable window.   Is there a way to add those to the list of choices I see when I right click to the right of the "Help" menu choice in virtuoso?  I get the normal popup with choices "assistants" and "toolbars".

2) I have some code which generates a toolbar that has a "category" combo box and then based on which category is picked the toolbar gets populated with a bunch of actions.  This seems to be working as desired.  In the callback for that combo, I use hiDeleteToolBarItem to remove the old list of actions and hiAddToolbarItems add the new ones. 

Unfortunately, I think that is is actually a dockable window I ultimately want instead of a toolbar because I wanted to have a tab for it like my other docked assistants (Palette, Navigator, Annotation Browser).  I tried adding the toolbar to a dockable window I created but it is pretty easy to accidentally drag the toolbar out of that dockable window and then I can't get it to stick back in so I think that isn't really the right approach.

Should I be using my actions (created with hiCreateAction) and adding them to a fixed menu that I put in the dockable window?

In case someone else is looking for code samples:

;; creating a simple dockable window

formId = hiCreateAppForm(
   ?name 'myAppForm
   ?fields list(
      hiCreateLabel( ?name 'label1 ?labelText "My Label" )
      hiCreateButton(?name 'button1 ?buttonText "My Button" ?callback "printf(\"button 1 callback\n\")") 
      hiCreateComboField(?name 'combo1 ?prompt "My Combo" ?items list("choice1" "choice2" "choice2"))
   )
)
winId = hiCreateDockWindow(
   ?appType "layout"
   ?widgetType "form"
   ?handle 'myDockWin
   ?form formId
   ?scrollBar t
   ?title "My Dock Window"
)
mainSession = getCurrentWindow()->sessionWindow
hiDockWindow(?window winId ?session mainSession ?side 'left)

;; How to cause the dockable window to be tabbed like my other assistants (like Navigator, Palette, and Annotation Browser) already are?

;; how to add to the list of assistants in the popup menu that shows other assistants?  Or do I just need to add something to a custom pulldown menu that is added to the banner that toggles my dockable window mapped/unmapped

;; create some actions

act1 = hiCreateAction(?name 'act1 ?iconText "Action 1" ?callback "printf(\"action 1\n\")")

act2 = hiCreateAction(?name 'act2 ?iconText "Action 2" ?callback "printf(\"action 2\n\")")

;; create a toolbar

toolbar = hiCreateToolbar(?name 'mytoolbar ?title "My Toolbar" ?toolButtonStyle 'textOnly)

hiAddToolbarItem(toolbar, act1)

hiAddToolbarItem(toolbar, act2)

w=getCurrentWindow()

hiPlaceToolbar(w, toolbar, 'left)

;; how to add to the popup menu list of toolbars?

;; can my actions be placed into the form in the dockable window instead of a toolbar?
