I've enhanced the column-wise PrimeGrid preferences web page. It's a LOT more useful than it used to be.
If one percent of you know what I'm talking about, I'll be very surprised. Nobody probably ever used that page because it was useless.
On the left, Click on "Your account", then click on "PrimeGrid Preferences", then at the very top of the page click on "Switch View".
