Ah, I didn't know this happened! But, I'm afraid it's not for me. I suppose with everything there will be those who dislike it.
Upon downloading it, and I'm scrolling through all the items, I'm find it quite difficult to find what I need. Dare I say that it's even more difficult to find what I need with this than 4.3. While yes, all the new subcategories some might find more helpful than digging through the unorganized mess of 4.3, I simply find that it throws me off. After literally years of knowing that all the neck items are after muzzle items due to the old way items were sorted, with everything suddenly being in the same place, it's now extremely difficult to find what you need. For me, I am very heavy on necklace items and I cannot find any of them; I can only find a plethora of head items. And let's just talk about the FH update for a moment. The FH update brought with it a slightly extended list of default items, those being commonly used items from Legendary at the very top, making them easier to access. Two types of antlers, both ear feather items, and a few other things. Now that these items are also filtered in with the rest of the items, these commonly used items are now harder to find than they've ever been in the history of items.
Now, I love that you've recoloured the bandanas! It's awesome, but it'll go to waste if the people who need them most are simply struggling to find them, or not finding them in the first place and giving up. An easier way to have gone about this would have been to simply tag your items on at the end, like with all Legendary updates. The FH update items would still be in place, no one would have item disconnect if they didn't have this, and we wouldn't have to get used to a new system of navigation with the items.
I understand that you were trying to make it easier for you and some others who found the old system confusing and difficult to navigate, but I personally just find it to be causing more problems than the single problem it was trying to solve. I find that this isn't something I'll be using, and re-downloading 4.3 so I don't have severe item disconnect. I'm sorry if I came off very negative or if it even came off as hateful, I'm just stating the problems I found with it.
