Omissions in QTabs component

rubs

The QTabs component is quite useful, but in my opinion it has some omissions:

It’s not redrawn automatically when a QTab item is inserted or removed – especially the navigation arrows visibility doesn’t change. I kinda solved this one by using a ready flag that gets updated when a new item is inserted, but it would be easier if the component did it already.
When inserted, new tabs that go past the current width are not scrolled into view. Apparently there are not events for doing this.
The mouse scroll wheel doesn’t do anything. Capturing the wheel events and sending clicks to the arrows didn’t work for me:

wheel_scroll: function(event)
{
  let arrows = this.$el.getElementsByClassName('q-tabs__arrow');
  let evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
  // Here I chose one arrow for testing, but nothing happened:
  arrows[1].dispatchEvent(evt);
}

It would be nice if users were able to drag individual tabs to change their order.

Would exposing some extra events and properties allow these actions? I don’t know. Any help is appreciated. Thanks!
