It's not necessary to move the calling macro, Open New Window With 4 Tabs, into the ⋮Finder Assistant group. In fact, I suggest you move it to one of your other macro groups (or to Global Macro Group) since it's not part of Finder Assistant; instead it's just leveraging the subroutines within.
I think I understand your comment, but just to make sure it's working as I expect...
You got one new window (with four tabs), not four windows, right?
You're welcome!
As you are playing, you might want to refer to the magenta header comment at the top of sub 𝗌.𝗳𝗻𝗱⇾NewTabOrWindowInSpace (located in the ⋮Finder Assistant group).
Also, feel free to ask follow-up questions.
BTW, I use 16 Mission Control Desktop Spaces on my MacBook Pro. Space within the sub name, 𝗌.𝗳𝗻𝗱⇾NewTabOrWindowInSpace, is referring to the currently open Mission Control Space. If you use only one space, then the reference in the subroutine name is moot. (If I've just confused you, ignore this paragraph.
