Hey just installed lion. and I am pretty much always use column view for the finder. I noticed in Lion there is not an obvious way to hide the preview of a picture or video file when one is selected. There used to be a little triangle to open/close it (like folders in list view have). I usually leave it closed (which will leave it closed for all items) because sometimes (especially for large, non apple file type movie files) the finder hangs a bit when trying to generate said preview.
any way is there a setting somewhere to turn this off?
Edit (forget it im an idiot found it in view preferences where it should be.)
