Whiteboard
The whiteboard lets anyone watching a screen share draw on top of it. Useful for “point at this”, code reviews, or just decorating a movie night.
Strokes are sent through the server in real time, so every viewer sees them as they are drawn.
Screenshot placeholder: stream with annotations layered on top.
How it works
Section titled “How it works”Each stroke is a small batch of points (position, color, width) sent as a plugin-data message. The server forwards the message to every participant in the channel. There is no per-stroke persistence; when the stream ends, the strokes are cleared.
The whiteboard is a client-side feature. There are no documented
server MUMBLE_CONFIG_* or plugin.* keys for tuning it.
Compatibility

Pitfalls
