I used Rajneel's example and made a few more tweaks like moving the "Options" (filter, quick grading settings etc.) to the top and collapsed. Also combined the Quick Feedback in the Marker Feedback column because it appeared twice.
Many thanks to Rajneel for sharing the customisations. If anyone would like my code just send me a message.
