Sure:
One of the complaints that we have is that because the table is so long, horizontally and vertically, using the mouse scroll button to move up and down the screen, actually moves the grid to the left and right.
One of the other complaints is when clicking on the horizontal bar, it doesn’t snap to that exact location on the grid.
We have also received some requests to see if we can have a horizontal scrollbar at the top of the grid.
As for the iFrame, it was only one idea that I had. I’m pretty sure there are better ideas out there.
