I just noticed that when you cut, all layers underneath get cut as well. I am fairly certain that previously this was not the case and you could cut out just a single layer by doing ctrl-x (in my case cmnd-x). I wanted to know where the code for this is located so I can comment it out (in my mod). I looked through the source a little, but I couldn't find it exactly. I think it has something to do with forcing a stacking check.

Ok thanks, ill take a look there.
