Undo button userscript?

I was wondering if there is an “Undo” button Userscript. This feature is present in Flaming Durtles Android app but I couldn’t find an alternative for the web app, and I’m looking for this because I have often found myself needing to undo an answer simply because of a typo in the Reading answer.

Thanks! This is exactly what I was looking for.

How do you get to level 19 without using undo? I have way too much dead space between my brain and my fingers to do without undo.

Very painfully.
