Speed problem with advanced shopping list - list shifter a solution?

Yeah, you can do this much faster with List Shifter. I’m actually working on a little example and video of this that explains how you’d do it. This was useful because it exposed a bug in certain Process List operators.

While you wait for that (might be a day or two as I continue to be super-busy with my non-Bubble gig), you might want to watch my intro to Process List in the video posted in my comment here: List Shifter: Reverse, Rotate, Swap and ITERATE (Loop) Over Bubble Lists | Now at v1.4: Adds Numeric Option, GET INDEX Action.
