This was fun, my two cents:

I think backspace should count as a keystroke within the same sentence for the purpose of delaying deletion.

It would be really cool for this to dump your content into a rich text editor when your time is up for spell check, cleaning, and editing before download.

So I wanted backspace too, but thinking about it, even within the same sentence it would damage the purpose of freewriting which is to stop editing and get words flowing out of your head and into somewhere you can be objective about it later. On a five minute run (my initial one) I found myself running up against the red words a few times as I self-edited what I wanted to say, and it helped me stop that and move forward again. I'm pretty sure I didn't break the sentence barrier those times either, but then, as you can tell, especially from this pernicious example, I'm prone to more lengthy run-on sentences — overloaded and dripping with information in a languid fashion.
