The Qps Graphical File (QGF) containing Annotations can be used as a kind of overlay chart with Waypoints/Lines/Routes/Area and shown with symbols. User can attached pictures, files and add comments. It also offers a search function which can be really useful, but the items cannot be used in the line planning or to navigate to.
With Alt+F9 user can quickly add a (way)point, for the active tracking point, and add a comment and therefore can be used as a kind of eventing without the need to setup the whole eventing with *.ico pictures. But again the user cannot use these point in the line planing for navigation when they want to return to those locations
Add the option to select the Annotation (QGFanno) file under line planning
