Yuk. It has come a long way, but still has a long way to go. If users start a workflow and realize they have put a step in the wrong place, you can't drag and drop it anywhere. You can't cut and paste the condition or actions and you bascially have to start all over again (as an end user). If you aren't an end user, you can actually open up the XOML file and move the items around, but its not a step you should have to do!
