Feature Request: Bulk Channel Mute Editor

Currently to mute a bunch of channels on a server I need to go to each one individually, right-click on it and choose "Mute". On a server with a lot of Channels this takes a frustrating amount of time.

Instead it would be nice to have an interface that lists all the Channels on a server and offers a checkbox to mute each one individually. It would be nice to have a Check/Uncheck All button as well so I have the option to mute all Channels quickly and only un-mute the ones I care about.
