Code review comment for lp:~nik90/ubuntu-clock-app/lock-portrait-orientation

@Jonas, Because while the flickable might make the alarm page useable in landscape mode, clock app was always meant to run in the side-stage and never designed for the landscape mode. Clock app is also in maintenance mode until pretty much 16.04 when we get Timer and Stopwatch designs. Until then I would rather keep it locked in portrait mode and not make any invasive code changes for landscape support.
