Hi,
Extracted from this idea is here a suggestion for improved artwork of stacked shift registers:

On the left is how stacked shift registers currently looks like, on the right the suggested graphics instead. The reason behind the idea not so much the smaller footprint, but more that it today is hard to distinguish between a stacked shift register and several single shift registers close together.
Cheers,

Changes present in LabVIEW NXG. Shift registers with stacked elements have a different appearance than individual shift register terminals.
