When troubleshooting issues with data limitations, I often need to check with a Smartsheet specialist about the number of cells used on a sheet. They will be able to refresh a view and find this to compare to my calculations of rows X columns and/or the little gray tooltips displaying in the bottom-right of a sheet when you select cells.
I believe it would save me and support time if I were able to see Smartsheet's calculations of my usage of cells and formulas. Through trial and error, I could determine whether and how to configure or divide my sheet.
Add this and any other metadata to the properties window for a sheet.
