All you had to do was go to the scan list tab, selected Scan list 91, highlighted the objects in that scan list and clicked on the "scan list" column unchecked 91 and checked 1. Repeated for the other 3 scanlists.
Unless you have objects with multiple scanlist assignments. Then you would have to go to each unique scanlist selection to do the switch, which can be a pain.
Also, he was saying he had to move #1 to #5, #2 to #6, etc. all the way up in order to free up the space.
When I program, I leave open scanlists throughout. And I use this productively. I skip three in a row. On the first and second, leave the scanlist name empty. On the middle, label it as a header for the next set of scanlists. This way, you have some flexibility should you need to reorganize later, and you have a nice header to help you keep your head on straight.
Drag and drop flexibility for scanlists, v-scanner folder, etc. should be a basic.
Let's face it, though, unless potential customers are astute enough to read about these things beforehand, and each one of them contacts the company to let them know why they didn't buy the product, any improvements are going to be slow and gradual.
That said, I very much appreciate what improvements have been made this year. I assume fixes such as having the correct tab order are a must to begin any sort of accessibility for the blind.
