"Fix" resolutions represent a proposed solution to one or many issues in the application. They are usually created to make sure that the related issues get eventually dealt with by someone in the development team.
Sonargraph allows to define specific "TODO" tasks for the different system elements. Those tasks can be assigned to a member of the development team to take care of. To define a TODO task, right click on the element and select "New TODO" in the context menu.
The "Fix" and "TODO" tasks are listed in the Tasks view.
