I have been testing the window labels. Please let me know if any of these observations are not correct.
Of the choices I have available in the US version of AC12, only the "louver identifier_NCS 12" automatically shows up at the center of the window in the elevation. The rest seem to relate to a corner and are difficult to select and move after placing them.
Fortunately, the "louver identifier" will show the ID on the elevation and has the US standard diamond shape, which is all I want.
The same window labels are not as good on the plan, because they don't come in at the center of the window. The NCS dimension marker of the window library part seems to be easier to use on the plan view.
In any case, turning the label on on the elevation does not make it show up on the plan, and vice versa. They have to be done separately.
