Thank you for your help. Setting to '0' I get no stock levels other than 'out of stock' for multi or single variable products. Set to '2' I got stock levels for double variable, but still nadda for singles. I fiddled with Option Name Mgr config, where I had both my option names (Size, Colour) set to 'SbA Select List'. By changing Size option to 'Dropdown' and either leaving Colour as 'SbA' or changing also to 'Dropdown' I get the stock levels showing on both multi and single variable products. Yay.
Curiously, since I couldn't stop fiddling, I experimented with the other option types in the Option Name Mgr config - radio, checkbox, text - in all of these the single variable products changed to the style selected, but the multi variable products all stayed as dropdowns with the stock showing. Also curiously, under no settings could I get colour swatches to show up. (I don't really need them as my photos cover it - I used the swatches in 1.3.9 site where my SbyA was in grid format.)
Realize that you've found some settings that work, but double check your configuration settings in the stock section regarding some of those settings in relation to single attribute product and the SBA dropdown. If the single SBA dropdowns have been affected, then I would say I've done something wrong because potteryhouse and jeking had worked to make sure that single attribute product (items having only one option name associated) functioned properly and I have tried not to impact that
As for the case where multiple attributes are used (more than one option name), at this time if Dynamic Dropdowns is on for multiple attributes, everything with multiple attributes will be presented as a dropdown. And no it's not just because the plugin is called that, there is the possibility already builtin to use radioboxes, but for me? One thing at a time. :)
Images: supposedly there is a way to work it with single attributes (again not using the Dynamic Dropdown single attributes option) to show images with the attributes. That was something p&j worked on to completion/success. The multiple attributes takes a little work to get there but there is a plan to provide the maximum flexibility in image setup.
