Closed playmobil42 closed 4 years ago

Closes #34

Changes:

Implement BACKGROUNDSLIDESHOW_PREVIOUS to back up one image.
Comment out Log messages for notifications so they don't flood the browser console (clock sends one once per second).
Cleanup: use early returns in updateImage() to reduce nesting - no behavior change.
