Support of vertical mode

[cyphersnake]

Very cool project! For a quick review some project is great. Unfortunately, to work correctly with vertical monitors, the ability to configure the position of the sections should be added (or if I just lost it, I apologize and ask you to point me to this configuration)

What it looks like now

Since the percentage of people who use this screen position is unfairly small, I can do this feature myself!

Thank you! Yeah - as of right now, there's no way to configure the positions of the sections. I don't think this should be too hard to implement, but let me know if you want me to go ahead and try doing it. The main place to look is the draw method of App! That method orchestrates all the panes and their sizes.
