Mood Wall Control is the phone app for adding emojis to the shared /mood-wall/ display.

Open it by scanning the QR code on the Mood Wall display. You can also open /mood-wall-c/?r=<room> directly if you know the room ID.
/mood-wall/ is open on the shared display.The control is designed for portrait phone use with large tap targets.
You can keep up to 3 emojis active at once.
Emoji buttons work like toggles:
Selected emojis stay highlighted on your phone so you can see your current choices.
The picker is grouped to make choices easier:
Use the group that best fits the mood you want to share.
The control shows:
If your phone refreshes, it asks the display for the latest wall state. Where browser storage is available, the phone keeps the same participant ID and can continue changing its existing emoji choices.
If the shared display is not open in the room, the control can connect but changes will not appear on a wall until a /mood-wall/ display is connected.
