Signal Notification Groups
Most of the teams I work with these days use the Signal app for messaging. When doing deep work, it is handy to mute noisy channels. But is there a way to mute everyone? Yes, with notification groups. The neat thing is that you still allow certain people to notify you or set it so that @ mentions still come through. You could also mute most of the groups you are in, but keep the one for the project you are working on. This allows you to monitor a bunch of stuff, but still only get notifications for things you are interested in.
