pinch in n out inside folders

[miladgh]

i noticed that pinchin in and out inside folders (for increasing/decreasing the size of the icons) doesn't work?
why is this disabled? any way to bring it back?

how about drag lock? i can't find this either. :-(

found the drag lock thing. it's in universal access, trackpad tab.

anyone has any idea how to enable pinch in n out inside folders? I don't wanna use the slider at the bottom right corner. i wanna use the trackpad for this. :-(
