Projects can be a hub for all the parts required to get the big job done. Linking tasks and appointments you have in other parts of Time & Chaos to a project does require you to learn a new skill: Drag, Hover, and Drop
Drag - just find an item on the display and click and hold on the item to start dragging it
Hover - from the screen shot on the left, you should see the hover zone right over the Projects button in the lower left corner of our screen. Once you mouse-over this area, the section above will display the Project Drop List with all of your existing projects displayed. (Don't let go of the item yet!)
Drop - move your mouse up to this new Project Drop List window and drop it on an existing project (or even New Project) to link it up.
