As workflows get more and more complex, I'd like an additional tool to help differentiate sections of workflows. One thought that popped into my mind was a control in sequences that would allow you to make a box appear around sequences in workflow designer to make them more visible. Even better would be the ability to make that box shaded or outlined in a different color. 

This type of option would presumably even be something useful in the new server down the road, or to have as an option in forms to differentiate different paths. 

I tend to add sequences in to differentiate different sections. But the more important reason I use it is when working with someone that has a test system versus a live system - controls that have things I need to change between Live and Test (usually SDK scripts and/or Database connections) I put inside a sequence that will have a IN CAPS message reminding them that the control needs to be changed (and sometimes a message reminding what needs to change)
