The screenshot makes it seem like you're going to copypasta RTB, change names ("Add-Ons Manager", "Chat", etc), then add a couple useless features and declare it your own. Then, when you're called out on what you did, you'll bring up that time when you were butthurt about Red_Guy remaking your mining mod into something far better as your defense.
Unless Ephi dies, I don't see how you are going to compete with RTB.
