If I understand correctly the logic, it should be two columns.
At columns 2, the nodes attributes you can edit-in-place.

For example

[-]-Point A(1;2)
�| � |
�| � |--- Free point
�| � |--- Name: A
�| � |--- position: 1@2
�| � |--- shape: =o v=
�| � |--- size: round
�| � |--- color: red
�|
[+]-Point B(5;5)
�|
[+]-Segment [AB]
