Very nice enhancement. Thanks.

Are you sure that specifying the titleTemplateUrl in the config phase with the dashboardProvider.widget(name, widget) function is working properly?

I tried setting it on adfWidgetAdded and it is working but I can't get it working this way:

dashboardProvider
    .widget('sample', {
        title: 'Markdown',
        description: 'Markdown widget',
        controller: 'TestCtrl',
        templateUrl: '{widgetsPath}/widget-template.html',
        titleTemplateUrl: '{widgetsPath}/custom-widget-title.html',
        collapsible: true,
    })
...

Same is for the collapsible feature. Could you please take a look at it?

It should work with titleTemplateURL can you check the {widgetpath }. May be it is not fetching the path. The example for the above can be seen in sample02 or sample03 tab.
Let me know still if you are not able to figure it out.

I just saw my issue is solved, but not yet merged: #139
It's not about the widgetsPath, otherwise my widget wouldn't be rendered at all, because it's widgetTemplate is in there too.
The sample is working because it set's the titleTemplateUrl on adfWidgetAdded, but that's too late for me and I also have different titleTemplateUrls depending on the widget type and setting it in adfWidgetAdded is not flexible.

Hope your issue is solved..but adfWidgetAdded event , when you add new widget this event help you to set titleTemplatURL dynamic.

Yes, thank you!
I will wait for the new release and using the adfWidgetAdded event is a way to avoid the bug until the new release comes.

If you still want that release ..you can pull my branch which you are looking for ..
