[Interest] automatic UI updates as the result of QML file modifications

[Alexander Ivash]

>> Yes.  I’ve done this.  I have a realtime coding environment in which the
running app will reload and redraw qml on file change.  It’s relatively
easy to setup.  I’ve even set it up so that it’ll draw iPad and iPhone
sized windows next to a reduced desktop window on my mac desktop machine.

That's really cool! But how do you reload not root QML files?

p.s. I think having such functionality in Qt out-of-box would be a killer
feature.
