For those with short memories, PR1.0 had the option to choose swiping down to close app. By default this was turned off and had to be enabled.

IIRC PR1.1 enabled this by default. However with PR1.3, mcompositor seems to have some changes hence why SwipeManager, the app, doesn't work properly now. Earlier it seemed like the four way direction swiping was not hard-coded but now it looks to be so hence the jarring transition when changing the mcompositor.conf to exhibit not default behavior.
