commit a70d1673103dccc4bbf52ed5d55a7086a18bf0e6 Author: Damian Johnson atagar@torproject.org Date: Tue Oct 20 10:03:53 2015 -0700

We might need to do something smart here but for now this belongs in the display logic. --- nyx/config_panel.py | 46 ++++++++++------------------------------------ 1 file changed, 10 insertions(+), 36 deletions(-)
