Hi there! For solving this problem, I need to update the plugin for changing children layers. In this period, I'm a little busy with some stuff, but in the near future, I'll make an update :)
Hi! You may have not see it, but a few days ago I reported an issue I have with your plugin "Keyboard Input Window - for RPG MAKER MV". Please don't hesitate to tell me how to fix it when you can!
