Code review comment for lp:~zsombi/ubuntu-ui-toolkit/dynamic-tabs

Tab.qml:

    QtObject {
        id: internal
        property int index: -1
        property bool inserted: false
        property bool dynamic: false
        property bool removedFromTabs: false
    }

Can you add a short description to these properties?
What does dynamic mean? Inserted means it is inside a Tabs, or only true if inserted using insert()?
