If you open the Visokio Scheduler to the main window, you only have the option to add, edit, and remove the task. Please refer to the below screenshot.
I would like to be able to move the chains up or down to get them in the correct order. I find that moving around directly in the config.xml file is time consuming and unsafe from a production standpoint. Can you please add the up/down to the top level page as you already have created under the chain action window per the below screenshot.
