labeling of the elements

Yes no big problem, you can make it yourself.
use the edit element function to make the roundedlabel, when time i will make them in weekend.
then make also the dot as separate element.
on both make 4 connections.
on the diagram insert both and fill in the text field.
then put a wire in between them.
if you make a link (previous next you can make a list of all on another page.
another way is to define them as a terminal.

Why do not use Qet editor for drawing your rounded label?
Dxf converter don't convert binary files.

that was the dot, now the buble.

But How do I connect the text inside the buble vith the name of the actual element?
