Haha, a few years ago I created a Chrome extension called "Writer's Block" that would delete everything in the textarea if the user pressed backspace/delete. I used it a lot myself for a while and it got me into the habit of writing without premature editing. I never got around to actually releasing it.

Thank you so much for making it, when I started getting into the habit of digital journal, it had helped me a lot to not fix grammar and to not cringe at the things I've just written down.
