Couple of things, not sure how many have been said.
Bug: When i find an item then switch it to a different folder. Sometimes that item will not appear on the decomposing page. I have to switch folders again to get it to show up.
Suggestions: biggest issue with new BP is without fshelper working everything has to be done 1 click at a time. Please either make it so page doesn't refresh every click or at least when you multi select potions or items then right click and select to use them, use all items/potions selected not just a single one.
