For some reason, Adobe has dropped the option to filter the comments list according to the color of the comment in version X of Acrobat. So I decided to jump to the rescue of those who depended on this feature, or just found it useful, and created a script which allows you to do it once again.
You can select the color you want to filter from a list of pre-defined colors, or just click on a comment with the color you want to use and then select the last option in the list: "Selected Comment Color". The script will then identify this color and will only present comments with the same color.

Here's how it works:
1. Select the comment color you want to see from the list

2. Now only the comments with this color are visible (even in the built-in Comments List!)

3. We remove one of the comments, and now we want to restore the comments we've hidden...

4. We're back to the original situation, with our edits in tact.

It's as simple as that...
