Do you mean, can you select which items appear for subs, follows, or raids? Because we do have that feature! And the option to pick how many items drop with each. You can also set items as rare or ultra rare and they have a chance to drop with any type, and you can make them as rare or common as you'd like. (If you meant something else feel free to let me know. I have a lot of plans for the app already, but I'm always open to new input and ideas.)
Oh Okay! I didn't know if you added a kind of variation feature or not. Thank You for answering my questions. I've actually thought about starting a Stream/Video Series of sorts where I try different VTuber Software/Apps on-stream like yours and HONK! to name a few. I even made an itch.io collection for any VTuber Apps I want to try.
