I am looking at upgrading our copy of GCSE companion and noticed some new teacher features.
If you go to:

Click on my work on the left then mark now next to a kids name in the main frame.
I especially liked the idea of displaying the mark scheme answer to the teacher when you are marking a short answers. Also the 'tick' / 'cross' buttons are interesting.
