[Feature Request] Don't reset input and allow backspace

[reformedp]

Use case: I would like to use this to memorise sentences. If I entered something wrongly, I would like to backspace and continue from there instead of starting from the beginning.

I have made some changes to src/pages/Typing/components/WordPanel/components/Word/index.tsx to turn off resetting input, but it currently does not register backspace.

I am willing to make changes and develop this feature locally myself. Hope that you can point me in the right direction.
