This section details on the original issue you should resolve

<issue_title>It doesn't copy comment from another pad</issue_title>
<issue_description>When I paste a text commented from another pad doesn't bring the whole comment just the text. It's shown the text with the background set to yellow.
Set the background to yellow makes the user confused but it seems to be easy to fix it just changing the comment class to something unique to the pad. IMHO copy the whole comment it'd be the expected behavior in this situation. Any idea how to solve it?
