On watching videos of others using the c9 command (for instance, this blog post where the feature was announced) the c9 command opens the files on the top pane, next to all the other files.
However, on mine it opens the files on the bottom pane next to the terminal. See this gif for my problem in action.
My question is, how do I make it open files in the top pane? Is there a way I can set the target pane? Thanks so much for your help.
