I felt limited by only six comments, so I made some small improvements which you might want to add.

Implemented the following features:
--
<sub>**Head list items are intended for users**, sub list items are intended for developers.</sub>

- Allow the user to enter an **unlimited amount of comments**:

  - Based the script on the *local storage*, while using `comments` only for initial data or to reset.
  - *Refactored* duplicate code & checks as `comments` behavior is replaced by `localStorage`.  
    &nbsp;

- **Scrollbar** for when the amount of comments exceeds the standard height.

- Added a link to allow the user to **toggle the visibility of descriptions**.

  - This is **remembered** by using the local storage.  
    &nbsp;

- **Improved see-through behavior** by hiding title and buttons and making it more transparent.

- **Fixed invalid info**: "User info detection doesn't work on CW answers, nor with deleted users."

  The box now either shows "This user is not registered." or hides.

- **Fixed greeting consistency**, it's now added again after editing comments.

To ensure that both versions don't conflict, **remove @Benjol's version first**!

**@Benjol:**  
If you want to add these to the extension, try a Diff and merge changes and perhaps improve my style.

I disabled automatic updates for testing purposes, don't migrate that change if you just copy/paste...
