Why was this functionality removed?

What is the latest version of the add-on that still has that functionality, and is it strongly inadvisable to use that version for that feature?

It was removed because I think it's bloat and other addons can do this better
The latest version that still has this feature should be v1.1.5

I would advise you to use Scrap (Junk Seller) instead

Thanks!

I actually just tested Scrap (Junk Seller) and while it does more easily identify scrap while also listing its sell price per unit, unforunately it does not also show sell price per stack =(, it does not have a native feature to highlight the least valuable scrap item/stack in inventory. I also don't event see a keybind for it in the settings.

Is there an addon for the addon that adds this functionality?

Can you try this standalone addon which has the previously removed code for flashing cheapest greys

Yeah that works great!

I think that feature is definitely worth having in the main addon. There are a lot of addons that show vendor price, but so far this is the only one I have found with his feature, which I think is genius and personally use quite frequently.

I personally think this feature should be in a separate addon. VendorPrice should just do one simple thing, show the price on mouseover

But I might upload FlashCheapestGrey to Curse after some refactoring
