For the workflow plasmoid I have implemented some features by using the 
above classes which
are available through the PopUpApplet class.
I will make a list of the features in order to see if there is a 
different way of implementing them
of if there is a chance to add some API.

1) Find the single image wallpaper for every activity. (For all the 
running and stopped activities I can find
it through the config files but when you create a new activity there is 
a time gap for storing the configuration
to the relevant files. The solution for me for these activities was to 
iterate the containments from corona
and find the wallpaper configuration)
------------------

2) Showing widgets for specific activity. I used the containment() found 
through corona():

     Plasma::Containment *currentContainment = getContainment(actId);
     if(currentContainment && currentContainment->view()){
currentContainment->view()->metaObject()->invokeMethod(currentContainment->view(),
"showWidgetExplorer");
     }
------------------------

3) Unlocking the widgets before showing the widgets explorer:
    I used the QActions from corona in order to achieve this
-----------------------

4) effectiveWId for the plasmoid. In order to enable window previews in 
the plasmoid I used
Plasma::WindowEffects::showWindowThumbnails which needs a WId. There are 
two circumstances
    a)if the plasmoid is in the Dashboard then the Dashboard WId changes 
every time the user shows Dashboard:
          I am catching the activeWindowChanged signal from 
KWindowSystem in order to check if the
          effectiveWId has changed for the Applet.
    b)when the plasmoid is in the panel the PopUps WId is found through 
KWindowSystem::windows()
          it is the last one in the list when the popup is first shown
-------------------------

5) I will open a new thread for this:
I think it would be good to add to plasma-desktop some qdbus functions 
for activityTemplates support.
I dont think that there is a way for a plasmoid to know which activity 
templates are installed in plasma-desktop
and also add an activity for a specific plugin. I think that all this 
could be exposed through qdbus without issues.
