Sometimes, I am waiting for something to happen in one project before another project can be started:

example:
install cool software
-waiting to install server os

And my other project is
Install server OS
-purchase software
-install server software

It would be cool if I could somehow tie in one waiting for to the completing of another task. Instead of looking at my waiting for list to see the task, waiting to install server os and check it off, when the Install server OS software project is complete, the waiting to install server OS is automatically completed and I can move forward on my project.
