Or at least KeySwift (but pretty sure stock android and ios have the same feature) does it:
Instead of having to press a specific letter, you can miss and press another close letter. For exemple if I want to write "hello" but I type instead "hekki" it correctly proposes "hello" as correction.
Same for "trsnskstd" and "translate", "ajithdr" and "another".
So instead of having 26 letters to press, you could make for example 6 groups of 4-5 letters, and let the computer decide which word you wanted to type.
Stuff like this is amazing though.
