I don’t have Niel’s skill level or much Mac familiarity either, but I will remember the idea. By intended parent folder, I mean the folder that I want to be directly above the new folder being created.
Example: Documents>ABC folder. I want the new XYZ folder to be directly under ABC, the intended Parent folder. I just googled the PC mag definition: A folder that is one level up from the current directory in a file hierarchy. So I am using that term correctly.
Your suggestion parallels the one by Zurarczurx, in net effect, and is also the best solution in my opinion. My overall problems with Finder seem to center on being unable to see what is between the folder I want to create and the remaining folder structure to the left of it in the column view. This is somewhat the case in List view, since when I go to create the new subfolder in say Level 4, I can no longer see Levels 1-3 to the left. Instead, all I can see is a blank area, after double clicking on the intended parent folder. The blank area is disorienting, like a tiny part of a map when I am used to seeing the broader map of the area I want to navigate.
This situation is admittedly tolerable, but I much prefer being able to potentially see the entire folder structure (as much of it as I want to see) while working on part of a folder structure. This is what File Explorer offers, and it is my major objection to the Mac, even though I am going ahead with using it. Someone who has been all Mac or mostly so might puzzle as to why I think this point is of any importance, much like I puzzle as to why anyone would think of designing Finder in the way that it is in this respect.
