Questions about GroupManager and the lib TaskManager

[Matthieu Gallien]

Hello,
I really want to find time to contribute back to KDE because I really 
appreciate all your work. So I am trying again to do some plasma related 
contributions.
I hope to be able to find time to work on porting the tasks data engine to the 
GroupManager and other new bits of TaskManager lib.
Is there anybody already working on that ?
Do you think it is a good idea to work on that ?

I have one concrete question about GroupManager. If I want to provide a 
dataengine, I would like to let the visualization decide about what tasks to 
show. How does this is related to this set of methods ?
    bool showOnlyCurrentScreen() const;
    void setShowOnlyCurrentScreen(bool);

    bool showOnlyCurrentDesktop() const;
    void setShowOnlyCurrentDesktop(bool);

    bool showOnlyMinimized() const;
    void setShowOnlyMinimized(bool);
Should I still use them through jobs ?

Thanks in advance
Best regards
