Hi Chris,
I hope you don't mind me answering in place of Steve, but we're very happy to have you on the forum, and thank you for your kind words about the Infinity.
We've started looking into a sharpness feature for the Infinity software, but at this point I wouldn't go so far as to say it'll be ready in the near future - at this point I can only say the hopefully future.
Also there aren't currently any plans to alter the power attachment - partly because once things are held too firmly in place, tripping over a wire becomes a disaster rather than a minor inconvenience! Though I wasn't aware of people having detachment problems with normal use - obviously if it turns out to be a common experience, then it's definitely something we'll look into.
I hope that helps, and I'm sorry I can't give you a firmer timeline on #1. And welcome again to the forum!
Jo
