In-line comments/notes in tasks, projects
I create somewhat complicated tasks that I like to add a lot of comments to. Right now I do this is the "Label" field of each a action. I sometimes use the anchor action at the top of the task and type in a large paragraph into the label field. Not sure if large text in the label fields can cause problems or excessive memory usage at runtime.
A simple dummy "comment" action would be a lot cleaner looking and could ignored at runtime.
