OK guys,
It’s make me frustrated to make a change how TV looks like how I want.
See my attachment, you’ll understand what I’m aiming to.

Yes, it’s a dirty core hacking.
I’ve tried to change the mutate_content.dynamic.php line 781 to move the $row[’description’] to another <tr>, but the description disappeared, even from the html source viewer.
<?php
echo "\t\t",'<tr style="height: 24px;"><td align="left" valign="top" width="150"><span class="warning">',$row['caption'],"</span>\n",
"\t\t\t",'<br /><span class="comment">',$row['description'],"</span></td>\n",
"\t\t\t",'<td valign="top" style="position:relative">',"\n",
"\t\t\t",renderFormElement($row['type'], $row['id'], $row['default_text'], $row['elements'], $tvPBV, ' style="width:300px;"'),"\n";
"\t\t</td></tr>\n";
can not be replace easily with
<?php
echo "\t\t",'<tr style="height: 24px;"><td align="left" valign="top" width="150"><span class="warning">',$row['caption'],"</span>\n",
"\t\t\t",'<br /><span class="comment">',$row['description'],"</span></td>\n",
"\t\t\t",'<td valign="top" style="position:relative">',"\n",
"\t\t\t",renderFormElement($row['type'], $row['id'], $row['default_text'], $row['elements'], $tvPBV, ' style="width:300px;"'),"\n";
"\t\t</td></tr>\n";
What am I missing here?
