Ok and one more thing...
I just added image view so when you are filtering out positions in 'Matches/Match errors' you can now click on the 'view' button to view the positions all in one go instead of playing through them individually.
This could be useful when generating a challenge or just a quick glance at the positions you have identified.
You can click on the images to view the actual position (and the correct answer) so you could make up your opinion on what you would play and then check the answer (without leaving any score trail on the server...). There is a back button on the board to get you back to the image view.
I have added this only on the commercial server as another carrot for you to be tempted by! :-)
But now I'll shut up for a while as I'm going on a vacation soon anyway...
