Terminal Split Pane: Why does split pane it merely duplicate what I type in the second pane? Why can I only type within the second pane? Is there a way to change the orientation of the split panes? I'm either missing something or this feature is totally useless/broken. Stack Icon Sizes: In the dock, when I view a folder stack in Grid, how do I change the icon size? They're like, goofy huge too me.
