Excellent, a completely new inventory module!
Well done Giang, an excellent start, but just a couple of issues I've had using it so far:
When I click on the new "Manage Inventory" button, I can't scroll in the pop-up. If I hold CTRL and click to open it then it seems to be OK. Hopefully we can also have filters and the SKU displayed soon too, takes a while to scroll through all my products.
The Out of stock Status of "Pre Order" is displayed even though I've selected a different status on the new product/inventory tab, and "Display Stock" does not appear to make any difference either. This is causing me a problem, I like to show availability times for my products not just "pre order"
