A more intuitive way to save/change a layout (seen in other apps) is like this:

Adjust the UI first: window size + position (or full-screen); menu/bar visibility + position; … (I think Ruler / Line Number / Outline Guide / … can be also included to save.)
Then use “Save Layout…” command, to save the current layout with a new name, or to replace a saved one.

(▲ And I think workspace saving can be also like this.)

This way, personally I think the “Options” list in [Customize: Layouts] can be simplified, and the “Save Current Window Position” button is not needed.
