Inline editing of product data values on product page (instead of clicking into each product to edit)

A feature we used to have on a competing product like storefeeder. Having the ability to change a products stock level on the products page (aka inline editings) rather than clicking into each product to make the changes, saves a fair bit of time if you are wanting to manually input stock levels. Other values that could be edited inline include pick bin locations, cost prices, prices etc. It is really handy as you can search for a group of products and edit them inline a bit like excel without having to click into each one, save, exit and search for the next product. Inline editing might be activated by a button at the top of the page or double clicking the value you want to edit, i cannot remember how it was done in our old system. Thanks Kieran
