I may have spoken too soon. I had some conflicts with my Friendly HUD, Item Sort Order and Better Icons mods where items were showing up in the wrong tabs or completely missing altogether. I do like that they separated weapons and armor as well as oil from potions from bombs. Very useful and much friendlier in that regard. The lack of uniform columns with the shared tabs is a minor annoyance. My alchemy/crafting tab, as noted, is also pretty laggy.
Overall, it's a good aesthetic improvement. Need to figure out why the level requirements from my quests section is missing though now... this update doesn't play nice with a whole bunch of updated mods.
