Toggle Hide Group 63
Change the hide state of group 63. There is no group 63. The maximum group is 32. Maybe in a future release.
Still keeping groups in mind. Possibly use groups during mix and routing setup, then disabling during mixing.
Possibly a combination of a group for every summing stack?

You can also automate a group. This lets you easily set the change for parameters of a group of channel strips over the course of a project. For example, you may wish to group all of your guitar channel strips together and have all of their relative volumes change at the same time throughout your project.
