Improve dual swipe gesture typing by delaying input

[makkonen]

I don't know if it's by happenstance or by design, but Heliboard supports dual-swipe typing (where two fingers swipe across keys simultaneously and the keyboard amasses the jumble into a word). I can't find any discussion of it here, so I'm not sure it's intentional behavior. It's often pretty hit or miss... but when it works it's great.

(This functionality also apparently appeared and disappeared in GBoard at one time, so possibly it's been in their libraries the whole time, but not exposed to users.)

It's also part of niche/beloved (but deprecated) keyboards nintype (aka keyboard69, aka keyboard71) and keymonk.

The way swiping works in nintype is slightly different. It doesn't commit a suggested word until you hit the spacebar, so you can string together multiple swipes and taps to compose a word. In Heliboard as soon as you lift both fingers off the keyboard, it submits.

Describe the solution you'd like
I'm not actually sure if this is possible, as I haven't looked to see how much freedom there is in how the gesture-typing library is called, but if there is a trigger for "submit gestured word", add a toggle to send that on tapping spacebar, rather than on completion of swiping. I can think of plenty of ways this could be impossible, but I think there's also a small chance that it's actually not that complicated.

Use case
Would provide for faster swipe-typing and hybrid swipe/tap-typing.

Describe alternatives you've considered (if any)
Using the keyboard as-is, as the hybrid dual-swipe/tap method still works, one must just be careful to keep at least one finger held down until the completion of the word.
