Nice to hear that.

Take a look at the "GUI toolkit" section of the manual. This should get you
further in understanding the use of layouts and containers.

Another entry point might be the new tutorial series we just started (3 parts
are available by now).

Is is really important where in the DOM the nodes are added? If you need to
position a widget in a specific way it should be possible with the help of a
layout manager. The reason why popup widgets are added directly to the top
level node (application root) is a technical one. It easily allows you to
position the widget with absolute coordinates and to be able to show the
widget above others.
If you need this kind of widget then the popup widget might be a good starting
point.

The "GUI toolkit" section I mentioned above.

Such a specific documentation is indeed missing, but maybe the "Custom Widgets"
article wil help you further.
