I just tried this out, and the need to double-tap was a total deal breaker making words like "success" a failure.

The other problem with the way this double tapping works is that I encountered missed spaces or other weirdness if I type too quickly. It's as if it's having trouble detecting new keydown events when another key is still down for a split second.

There is, understandably, a slight delay with double-tapping, so using simultaneous key presses can help improve speed when typing quickly. Thank you for your feedback.

Sorry if I was unclear, but that's the opposite of what I'm saying. It feels as if simultaneous keypresses are not working once I type faster than a certain speed because of the way double tapping is implemented.

I think I'd prefer tap and hold for the secondary character. Right now spelling is getting totally mangled no matter the technique of the user.

Since tap-and-hold has a longer delay, wouldn’t it be more suitable as a method for various extended characters in the multilingual versions? I will check whether there is any interference between simultaneous input and double-tap and take the necessary actions. Thank you for the feedback.

yeah, I agree. It feels pretty rough to me. On older feature phones, you could accelerate this with a right arrow key which would lock to the key for key duplicates like 'cc' in success. Definitely feels like this needs a dedicated key for doing that
