There is a potential drawback to enabling the feedback by default: the 
"Run with feedback" option has a user-editable "delay time", needed to 
make the animation visible, or at least slow enough to follow by eye.

Therefore, we would have to create a default value for the delay, which 
would, in turn, slow down the execution of all workflows. Probably not 
an issue with some of the simpler example WFs, but may be a problem with 
bigger/more intensive WFs, especially if users don't realize this is the
