The Groups List allows to quickly manage the groups of the session, and make use of them.

Each group has a Show checkbox to quickly toggle their visibility. Clicking an already selected group allows to rename it.

The context menu, reached by right clicking a group, allows for multiple mixing actions:

Create New Group From…	Creates a new group based on some track properties. The choice is: `Selection…` to create a group of all selected tracks `Record Enabled…` to create a group of all the tracks that are record enabled `Soloed…` to create a group of all the soloed tracks
Create New Group with Master From…	Acts exactly as the previous choice, but also creates a Control Master tied to these tracks.
Assign Selection to Control Master…	Allows to link all the selected tracks to a chosen Control Master, whether or not they belong to a group.
Assign Record Enabled to Control Master…	Allows to link all the record armed tracks to a chosen Control Master.
Assign Soloed to Control Master…	Allows to link all the soloed tracks to a chosen Control Master.
Enable All Groups	Enable all the groups, i.e. their selected properties are synchronized.
Disable All Groups	Disable all the groups, i.e. changing a property in a track won't affect the others.

When a group is selected, right clicking it adds the following menu entries:

Create New Group with Master From…	Acts exactly as the previous choice, but also creates a Control Master tied to these tracks.
Edit Group…	Shows the `Track/bus Group` window.
Collect Group	Rearranges the tracks/busses order to visually group together the tracks belonging to the same group.
Remove Group	Deletes the group (but not the tracks/busses belonging to this group).
Assign Group to Control Master…	Allows to link all the tracks in the group to a chosen VCA.
Add/Remove Subgroup Bus	Creates/removes a new bus connected to the Master, and send the output of all the tracks in the group to this new bus.
Add New Aux Bus (pre/post-fader)	Creates a new bus connected to the Master, and create Aux Sends (pre or post-fader) in all the tracks in the group to this new bus.

The + button under the list allows the creation of an (empty) group, while the − button deletes the selected group (but not the tracks in this group).
