It's been working fine, but if you change the 'Quantity' of an attribute in admin, the "Quantity for all variants" does not update to reflect the total number of items. A "Sync Quantities" fixes this, but why does this not happen automatically?
For some it is a feature, for others it can be a bug. A "clean" handling mechanism hasn't been developed, but there is this to consider and one of the things about continued development of this plugin.

There is no requirement that the sum of the individual variants must equal the sum of all possible products.

For example, a "product" could be made of a combination of individual attributes instead of a combination of attributes, take for example a product sold that has a size and a color of say a patch applied to it. There could be three sizes for example and a single patch quantity. When purchasing you can either add the patch or not. If there are 5 shirts of each of the three sizes and there happen to be only 8 patches. Should the total of the items be 23? Or really should it be15? What about for those that sell the item only if all options are available and therefore only 8?

Currently only variations that are fully defined by combination of attributes or those not having any combinations but instead all individual are best supported. There isn't yet a process incorporated to cleanly handle both on a single product.
