Cannot hide individual tabs

Here is a simple hack that I've been using that seems to work well:

Tab {
    property bool show: false //true to show or false to hide
    __isPageTreeNode: !show

    onShowChanged: {
        __isPageTreeNode = show
        parent.updateTabList()
    }
}

Sorry, the method I posted before actually breaks toolbars. Here is a better method that involves generating the list of tabs manually, taking into account the show property:

Tabs {
    id: tabs

    Tab {
        property bool show: // true to show or false to hide
        onShowChanged: {
            parent.tabList = tabs.customUpdateTabList(parent)
        }
    }

    function customUpdateTabList(tabsModel) {
        var list = [];
        for (var i=0; i < tabsModel.children.length; i++) {
            if (isTab(tabsModel.children[i])) list.push(tabsModel.children[i]);
        }
        return list
    }

    function isTab(item) {
        print("Checking tabs")
        if (item && item.hasOwnProperty("__isPageTreeNode")
                && item.__isPageTreeNode && item.hasOwnProperty("title")
                && item.hasOwnProperty("page")
                && (item.hasOwnProperty("show") ? item.show : true)) {
            return true;
        } else {
            return false;
        }
    }
}

dynamic tabs will land soon which can be used for this purpose
