With 11.1 we took some time to enhance many core scenarios in the pivot grid product. I Have covered some of the enhancements in the posts:
Collapsed State Memory Consumption Improvements (coming in v2011.1)
Unbound Field Values Memory Consumption Improvements (coming in v2011.1)
But there is more to cover… You can see the full list of new features at the What's New in DXperience v2011 vol 1 pages.
Here is a video of the improvements made to exporting and print preview for 11.1. I hope you enjoy!

More to come soon…
