Hi,
We've developed a patch that places a tab panel on top of moodle's course page, so now you can select wich week you want to see. Also, we've used ajax so that only the "current week" part of the page is reloaded when you click on the tabs, the visited weeks stay in memory, so if you go back to one of them it doesn't even reload anything at all.
Here's a sample video, we're making the final touches to the code and hope to release the patch in a day or two.
Comments, critics and suggestions are welcome
