I have not had time to try your editor, but it shows that it is a titanic work. This is worthy of great merits. Not even a great company has been able to implement something like that in its editor. In short, you have done the work of several engineers of the time being only one person. My utmost respect and I hope you get to show the new tools of your editor, I see nothing wrong with the animation tool implemented! Consider selling the second version of your editor, I am sure that many users (including me) would support you to promote this great tool. Best regards and happy new year!
