1.) Some of the herb "bundles" do not stack in the inventory - Belladonna bundle, Autumncrocus bundle, Daggerroot bundle, etc.
2.) It would be nice if the inventory didn't close when you read a book.
3.) The inventory some times scrolls back to the top if you are dragging items between characters and there is a scroll bar. If I am switching several items, it is a pain to have to scroll back down every time to find an open slot to drop the item in. It is kind of buggy and doesn't always do this, but it happens often enough people should be able to verify this.
4.) if I open a container (chest, box, bag, etc) then open my inventory and sort it, the container window closes. I then have to close inventory, re-open container, then re-open inventory to have both windows open after sorting. Please allow container windows to remain open while using the sort function in the inventory screen.
