There are grouping features missing. DAWs like Protools & Logic have several grouping options.
1. Each group should be possible to be edited. For example, I want to remove a channel from a group, or add more channels to an existing group.
2. Grouping attributes, for example I want to exclude Edit from a group. Or make a group only for edit, and not mix. Or select if the group will work for solo, mute, automation mode, input monitoring, record enable etc.
3. Temporarily disabling a group. If a group is assigned with an ID1, keyboard shortcut would be nice
4. Having grouped plugin options. For example a specific setting on Insert1 will be changed in all channels if they contain the same plugin on Insert 1.
