I just upgraded on one of my websites to 4.0.13 and it added a schedule button to every form I had setup. This appeared on my website and screwed it all up. Was your plan to add this schedule button automatically with the upgrade? This is a big problem for me as a website designer having to go back and remove this button off of every site is a lot of time and work. Please remove this automated feature, don't let your plugin mess up my websites.
