This is a sketch from my applications schoolclass administration site. Is there anything you would change to increate the user comfort/experience?
This sketch shows a relation of 3 entities and their dependencies. A schoolclass has many pupils. A pupil has many subjects. What you see in the wireframe is a formular with controls where you have to enter data.
My more detailed question would be for example:
1.) Should I put the Attach button in the Subject group box or should it stay over the related subjects datagrid?
