What does your feature entail?
Right now, opening a URL with Orion, e.g. running open -a "Orion" "https://kagi.com/", will open a new tab in the frontmost Orion window. This is good default behavior, but it would be great to have a configuration option to open a new window instead.
What are the exact ways that you see a user using your proposed feature?
Usually when I open a link from an external source, I want it open in a separate window, and it's an extra step to drag it into its own window. Might be a niche suggestion.
