Is it possible to the Align config, from all classes, to be the same type of AlignSpec of the widget documentation?
Support Forum
The Column's align config is regarding text-align, not positioning of the element.
The Scale's align config is regarding the positioning of the ticks, which usually doesn't need the specificity of the AlignSpec.
Perhaps Tool's align config could be changed, but I'll check with the team if that's the case and the possible impact/needed updates.
Best regards,
