1 is already planned for a future release, 2 is hmm a bit too much for mini i think, but i could do some research into it at some point ye :]
1. That's heartening to hear!
2. That's alright, I can get around it by downloading Krisp on my own and setting it as the microphone input for veadotube-mini. However, most of your audience won't know to do that, and so they won't have any noise cancellation. Hopefully you're able to attach one in natively.
