Swop Windows View and Applications View in Gnome Shell

If you want to avoid the annoying lag between Windows View and Applications View in Gnome Shell, try this hack:

Open viewSelector.js

gksudo gedit /usr/share/gnome-shell/js/ui/viewSelector.js

At line 407:

 addViewTab: function(id, title, pageActor, a11yIcon) {
        let viewTab = new ViewTab(id, title, pageActor, a11yIcon);
        this._tabs.push(viewTab);
        this._tabBox.add(viewTab.title);
        this._addTab(viewTab);
        this._activeTab= viewTab;
    },

And line number 469:

 _switchDefaultTab: function() {
        if (this._tabs.length > 0)
            this._switchTab(this._tabs[1]);
    },

Save and reset Gnome-Shell
