[Plugin: In-Context Comment] Suggestions for usability

I am looking for something like this plugin but found that I can not currently use it.

1 – In the post I put: <in-context-comment:here:Leave-a-reply>
But I did not see the tag, only the small box with “0”.

2 – The box shows a field that to me was the edit box !
Only after some try’s I realized that I had to click “Add a comment”.
Why not just open that immediately ?

3- Then pressing the COMMENT button, brings up:

To prevent spam, to comment you must login on either Facebook, Twitter or Google.
Your login info stays with Facebook, Twitter or Google, we only receive a verification from them that you have a valid account.

I do not want my users to require any of these. They are all registered as Subscriber or higher.

And btw, if you had mentioned the Facebook or Twitter requirement I could have saved myself the time to install the plugin.
