Something that I think got lost in the newer versions:
You copied a code snipped , switch to your block diagram and paste the code.
Currently (8.6.1) the code will show up highlighted in the center of the screen and you have to move it where you think it belongs.
I want to (right) click on a position in a diagram, hit Ctrl-V and the code show up at the click position.
I think it was there in the past, however I didn't found something in the options to turn that back on.
