I'd like to be able to add simple text - unassociated with any layer - to the main map canvas. This does not seem available at 3.22.3, nor have I seen it in earlier versions.
This would be similar to Layout > Add Item > Add Label, but without having to go into the Print Layout.
Searching the docs, plus an internet search, turned up nothing.
Annotation Layer
or aDecoration
(View -> Decorations -> Title/Copyright) what you are looking for?
