Fair. For me, I’m actively working with the customer, and they can forget something at any moment, and you have to go back, so you have to keep them all open as reference, until the end of the call. You do “prune” them as you go along though. I swear, though: the second you close out that tab they’ll have a question for that exact tab you just closed out. You also can’t memorize things because they always change, you just have to get good at navigating the resources. Maybe that’s a bit niche.
