If you want to record any tasks that you need to resolve in
your code, you can use the Tasks view, which is opened
in the normal way for opening views.
You can then enter tasks in your code by placing comments that contain
"TODO". In the following example, a TODO is shown in a source
file and the relevant entry in the Tasks view.
The Tasks view shows all tasks, even if the source file is not open. If you click a particular task, it will open the relevant source file. Note that you need to have the Mathematica project builder set for your project to process the TODO tasks. You can add this builder using the Mathematica project properties.
