How to add a New Action when viewing a Custom Perspective in OmniFocus 3? I have created a custom perspective in OmniFocus 3.11.2 for macOS. How do I add a New Action when viewing this perspective? Trying several approaches, I always just get an audible signal and nothing else happens.
Strategies that produce this:

menu bar File -&gt; New Action
the keystroke shortcut for File -&gt; New Action
the Return key

No combination of grouping or sorting has enabled me to add a New Action.
Background: my custom perspective filter rules only show actions that are

Available
In an active project
Contained within a few projects or folders

Thanks!
It's not possible to add a new action while viewing a custom perspective, as it's not possible to know where to put the action. Perspectives can combine projects, tags, etc., so there's no simple destination for the new action.
To create a new action from anywhere including a custom perspective, use Quick Entry.
