It's a very niche feature, but the only thing on my wishlist that kBonk doesn't do is that there's not a way to integrate it to a bot or send it a web request to trigger bonks. If I could, say, trigger my "Throw Giant Chair" custom bonk by sending a web request of some sort to the bot, it would be easy enough to use the app with just about any streaming platform.
My particular niche use case is for dual streaming to Twitch and YouTube. My bot read both chats, but has no way to trigger bonks; kbonk can only look for chat commands. So my workaround is if, say, someone on YT uses !throwChair, then my Twitch Chat Bot replies with "!throwChair" in Twitch chat so that kBonk can see it, then the bot responds again like it normally does (e.g. "Threw a chair at Sushi from @UserName). It could keep chat a lot cleaner if the bot didn't have to sort of "activate itself" by using a chat command on its own to talk to kBonk.
It would also, say, let me do something like "You got a PB in your speedrun!" ==> Bot tells kBonk to throw stuff to celebrate, or "You reset on the bleep-bleeping first boss again," and Bot tells kBonk to throw tomatoes.
