It works well, I was going to say my one big criticism is that the resulting doc and image could really use much better design (poor font sizes and inconsistent choices), but I think asking the maker who clearly isn't a designer to improve design would be a bad idea -- so I think it'll be much more useful if the tool had the options of:

1) Export in addition a set of images and google sheet with the steps on each row in a google drive folder. This way the data is much more valuable and I at least do things like write a script to use my own template for example.

2) Option to let us define the css used for the highlight and privacy mask - the current options don't look good on some sites and a blur is not appropriate in more sensitive cases where it needs to be completely blacked (legal, medical, etc).

In it's current state I would definitely use it for personal documentation and will hope that these options are implemented - which would make it perfect and could be used for orgs that are expected to have high quality designs.
