I don't remember all of UML anymore, but I still use sequence diagrams, activity diagrams and state diagrams. Using something standard is just easier than having to think about how to represent something, and then explain your representation to someone else. During the design phase, I'll usually write PlantUML code in IntelliJ and have the real-time preview fullscreen on another monitor. It's a nice setup.
