Skip Undo Function When Cutting Large Samples

Ok, undo rules in the sample editor so don’t get me wrong here… BUT I would like to have a progress window with cancel and skip when it is cutting or processing a sample. Like in Audition (Former CoolEdit). If I’m working on a huge sample and I select the area that I don’t need say 98% it will write this to disk to fallback. My harddisk is not that big, neither is it fast (laptop) so it gets a bit anoying after a while.

edit: I know I can switch buffering off but that’s not what I want…
