Suggestion/request: Highlighting changes or delta mode on columns

[cw1nte]

Some columns such as MAJFLT are useful, and would be more so if changes from previous value could be highlighted (or reverse video etc). More digits if the changed digits sub-string is longer will help draw the eye where the change is largest.
last display : 390178
next display: 390418 highlight 418
[This would help where the refresh is slower, typically I might use 3-5 s, and there is some time to apprehend significant data rather than everything in flux but conveying less (for me).]

To me this would only make sense on some columns and could be a column display option. A further refinement would be to have a threshold value... 0=no highlighting, 1=any change, N(>1)=changes greater than N.

Next alternative would be delta from previous value mode available for columns.

I hope you see some merit and fun in this!
