The discussion is about adding a “mute” feature to chat channels in the left sidebar. xan2622 proposes giving users the ability to mute channels to stop seeing notifications and the dot next to the channel name. However, khenmu points out that this feature already exists, albeit in a less convenient form, and provides step-by-step instructions on how to mute a channel. khenmu also agrees with the original suggestion. Meanwhile, mcwumbly suggests implementing a right-click context menu to provide easier access to channel controls like muting.
I think that it would make sense to give users the ability to mute channels (to stop seeing the dot next to the channel name) … to stop being notified of new replies in the channel.
