Array Display Should Snap Back to Last Element when Array Shortens

[SpaceX Trip]

If you have a user interface that has an array display, and the user has "scrolled" down, but then the array becomes shorter, they end up looking at an empty window.

You can code around this so that the software recognizes the user's position exceeds the array size and snaps the window back, but this is clunky.

There should be an option built into LabVIEW to automatically snap the array display back to the last set of elements if the array size shrinks.  I think this should be the behavior by default, and it should be something you can turn off if you need to leave an array display showing unpopulated elements for some reason.

The same should apply to multicolumn listboxes, etc.

I don't think that necessarily is what everybody wants. For instance, I often have indicators that I only use when debugging (say, they are the output of a subVI and the subVI's FP is never opened, unless I am debugging). I have sometimes wanted to understand why the 17th element is wrong (just a random number for illustration purpose). I set the ouput index to 17, and if the output array has a smaller size, I still want to look at index 17. I don't want it to snap back to the last element.

Unless I misunderstood the suggestion, I approve the option (how would it work though? I think there has been some suggestions to improve array indicators to allow snapping to the last position in the past), but I am not sure I would vote for it to be the default behavior.

This is related to this idea. Perhaps NI should standardize the way scroll bars function.
