This may be more of a feature request than question. What I would like to see is the ability for a product option stock update to impact the overall product stock.
If I sell Widgets in colors black and white, I should only have to manage the stock of the black and white versions and not the Widget product. The main product stock should be a cumulative stock of the versions/options.
I realize this doesn’t work for all product options, but maybe a check box, or the ability to add a section for product versions could fix this.
Updating inventory in two places is redundant unless I’m missing something.
