I’m probably missing something here, but in previous versions, right-clicking on a part in the Project window would produce a list of actions like erase, mute, cut etc., plus a whole list of other editing options.
Now all I see are the initial actions - no additional options.
Are they now gone? - I can not find a Preference for them.
Preferences → Editing → Tools → Pop-up toolbox on right-click.
If unchecked it should behave like you’re used to. If checked then right-click will pop-up the toolbox. You can also shift + click when that’s enabled to give you the additional options.
