UI is a great improvement. I still kinda hope there was a way to easier group items together, but there should be enough space now to not have to use containers too much.
Nothing really changed about a toilet chain, but group-ungroup all now doesn't require digging into option, and stealth all is a much needed addition.
JUMP DOESN'T THUMP ANYMORE. That is such a welcome change. Visually it seems snappier, but also bugs out - half of the time the character teleports to the destination, skiping "flying in the air" all together.
