I really love and appreciate the addon as the brilliant idea just suits my daily routine, just as people above my review.
It really is not working properly. And, really am I hope to see author improves or fixs it.
Guess it is still a miracle for not seeing any other obvious softwares or addons like this.
So I wish to see this addon be better.

While this extension does work, it is in desperate need of better documentation and an improved interface. Not mentioned in the description, a helper script is needed which connects the vim editor to the browser text being edited, a process which you are prompted to do on the first use. To edit a text field in vim, click on the extension icon, then on the text field.

So, unlike the previous reviewer, I read the docs, and I have gotten things working. It is pretty good.

I have been looking for something to replace a long abandoned extension which turned a text box into a VIM editor canvas. This requires a bit more work, but it is just as good!

I would suggest updating the docs to make the steps a bit more clear, but other than that, I am happy to have this back.
