As suggestion to 4.0 version, I'd like to add the next.

You have in tib_searchbar a button to count rows on dataset.

Based on it, is possible add a button or maybe, add a new component called
tib_calculus(for sample, or other name) that when clicked it performs a
sum,avg,max,min value of a numeric column from dataset?

PS: I am candidate to test the new version 4.0.
