Lack of debugging features makes wizards developing more complex. You can examine Nintex Bot approach that looks like one of the best. Kryon has only two options "Do it" and "Do it from this step". But this is not enought. But where is "Do this step only" options? Where is "Do selected steps" option? I need to have an opportunity to set some breakpoints to lauch different part of wizard to locate errors. Now i need to disable steps to run only needed and enable them each time. This makes developing very comlex. And where is "Do not play" option hotkey? See https://help.nintex.com/en-US/rpa/Botflow/Breakpoints.htm
Also there must be an option to execute single advanced command inside the step.
