Add the ability to drag-highlight more than just the rows that are on screen (scroll the grid while selecting cells)

You mean when you copy using the fill handle?

Need full functionality of the scroll function with the mouse. It gets very tedious copying a formula 10 cells and then hitting a hard stop. Then to continue you have to use the scroll bar or arrow keys, scroll over and start the copy function again.
