I think your post was best on the project development board. Non the less;
your "SeedClicker" script is a brilliant concept that addresses keylogger risks, but I did find one potential flaw. What about users who have added a passphrase to their seed phrase for extra security? and those words may not be listed amongst the BIP39 words, they would still need to type in the passphrase using a keyboard, which could expose them to the keyloggers.
But then I think this issue could be mitigated by integrating voice to text script. This would allow users to input their passphrase securely, without relying on keyboard input. It's not a perfect solution, but it could provide an additional layer of security for users who want to use passphrases.
