Also I want to highlight that heliboard devs together with NLNet are running an opt-in program to collect gesture typing data to make an open source library to further divorce from having to use closed source Google gesture library

Edit: p.s. if you somehow used to use this nifty iOS/android keyboard called nintype a decade ago where you can feature type using two fingers, heliboard also can do it. It’s awesome.
