To be fair, I’m the opposite of efficient with my tab usage. I close tabs often as soon as I switch to a different task, only to find out I still needed that tab.
I only just weeks ago discovered that tabs are kept open after rebooting (I had to turn power off during a session). That is how automatically I close tabs normally. A blessing and a curse.
Ha, I only knew the whispered line, never saw the conplete sketch. Brilliant.
