Any inventory mods being worked on//out yet?

I'd like to be able to sort through specific things while I'm at a vendor instead of it being one giant list to scroll through. Such as weapons category, ammo, misc items, like the regular inventory offers but when trading. It's a pain scrolling through the entire list.

I think you can change the item category of your and the merchant's inventory at the top of the barter screen? At least, in FO3 you could... So I bet you can do it in NV too.

The http://www.gamesas.com/index.php?/topic/1121454-wipzbeta-darnified-ui-f3/ is coming soon, which should reduce the amount of scrolling either way..

You can do that already. At the top of the inventory you'll notice a header with the category you're currently viewing, with arrows to either side with which you can sort through different item categories.
