Apparently WoW 7.1 has a new feature that displays green arrows on gear items in bags that the game determines are an upgrade for the character. There is a new related API feature, IsContainerItemAnUpgrade. I have not been seeing these upgrade arrows at all with my use of AdiBags.

Came here to report this, too. +1 for this feature, please! 👍

add to widgets\ItemButton.lua

after Line 305:

self:IsContainerItemAnUpgrade()

and after 335:

use the function in the next comment, this one crashed on resource bank

Martin ( p5hema2), I noticed that you have forked AdiBags. Was it for the sole purpose of implementing this fix, or do you have larger designs? I haven't done significant programming in decades, and hesitate to make a self-patch that I would have to reapply to any future updates. I'm already doing that with one addon, and every time I forget precisely what I did and where and must revisit it every time the addon is updated. My tools and technique are terribly primitive.

Personally, I have been playing the game a bit over two years; I came to it quite late in its evolution. From the beginning I was frustrated by the poorly designed and inflexible default UI, and sought out community solutions to it. I have been using AdiBags ever since, and could not play the game effectively without it.

Only for this feature. I am not used to wow addon development at all.

I implemented this feature only to have the green update arrows in my bag and want to share it with all other.

use this funtion, the above crashed on resource depod

function buttonProto:IsContainerItemAnUpgrade()	
	local itemIsUpgrade = IsContainerItemAnUpgrade(self:GetParent():GetID(), self:GetID());
	if ( itemIsUpgrade == nil and self.UpgradeIcon) then -- nil means not all the data was available to determine if this is an upgrade.
		self.UpgradeIcon:SetShown(false);
	elseif (self.UpgradeIcon) then
		self.UpgradeIcon:SetShown(itemIsUpgrade);
	end
end

I hope this gets rolled into Adirelle's next update!

I'm beginning to wonder if this will ever see the official light of day in AdiBags? Time to fork my own private version using p5hema2's insightful patch....

Addendum: Well, that didn't go well. I added both code snippets, but see no upgrade overlays for items that the Pawn tooltip insert declares is an upgrade. :-(
