It’s a great feature! I’m using it in my RTX RayTracing easy global settings tweaker ( RTX RayTracing easy global settings tweaker - Marketplace - Unreal Engine Forums ) and it allows me to have a panel with a lot of responsive buttons instead of classical call-in-editor custom events buttons, which are a chaos.
But it’s true that they can crash very often. I have needed to made some workaround to prevent all those crashes.
Thanks!
