Add a count for the number of cells reference in the sheet to the Activty Log and "Manage Reference" panel.
I am constantly hitting the 100,000 cells or 25,000,000 cells reached.
I want to get a heads up before my sheet crashes.
If there is a count, I can see if my changes are working or not.
The count should show which cell or column has the most references.
Also, make the columns adjustable, and add a scroll bar to the "Manage Reference" panel.
