Thank you for the feedback. Indeed such a functionality would be nice. One could solve this via another hand pose or in some way also with the existing hand poses. E.g. make a fist for say 2 seconds to clear the whole screen. Anything shorter will just issue an "undo".

YoHa uses tfjs.js which provides several backends for computation. One indeed uses WASM, the other one is WebGL based. The latter one is usually the more powerful one.
