I have one question now that plugins can be submitted, I just sat last weekend to learn how to extend the editor and now I am perfectly comfortable in creating anything that works just how landscape and foliage tool works. So if someone creates something like that which replicates the existing functionality , but in much better ways , like the ladder, stair and the handrail systems completely depend on actor blueprint classes , how about a more user friendly Slate based UI and simple mouse and keyboard shortcuts to do the very same functionality 10 times faster? Will that be considered unethical as well? (I am not going to do it though , can think of lots of great ideas that can be successfully converted as a plugin, without having to steal someone’s ideas(Ivy generator , anyone?))
