Stop Visualisations auto calculating when first creating them
Like in Excel you can turn off the autocalculate function.
I am creating tables etc and every-time i add a new column it starts calculating, and if i am using big volumes of data i get calculation timeouts without being able to check what is causing the issue.
It would be nice to have a preview stage where you can design you visualisation with a limited data set to see if it works first.
