Each Lane has a Commenting Lane below the section where the cues are located. You can place a single-point or ranged comment anywhere here. If that comment overlaps with a cue, it will also show up in that workspace. And if it overlaps with, say, a piece of audio that is audible, that comment will attach to that piece. This is useful when we get into the Workspace.

Clicking on a Lane will filter comments in the Commenting Pane on the right to only show comments written onto that lane. Clicking on a cue within a lane will filter the comments even further to only include the ones that are within the respective cue.
