Screenly is quite awesome but there are two features that is really lacks from a user standpoint.
- Orientation/Rotation of the screen. This is a super simple and basic modification of the /boot/config.txt so I don’t see why it was simple common sense to just integrate this into the settings page
- Being able to turn on/off the monitor at specific times (i.e. night mode). This is super simple to do using this script https://gist.github.com/AGWA/9874925
