The tooltips for my form show the field label before the tip. Is there a way to remove it?

Usability rules typically say to repeat the label of a field in the tooltip, so that is how BreezingForms has been set up. You can remove it with a hack though. To do so, open:

/administrator/components/com_breezingforms/libraries/crosstec/classes/BFQuickMode.php

Around line 1008 (build 856), look for this line:

$tipScript = '<script type="text/javascript"> <!--'."\n".'JQuery("#bfLabel'.$mdata['dbId'].'").qtip({ position:{adjust: { screen: true } }, content: "<b>'.addslashes(trim($mdata['label'])).'</b><br/>'.str_replace(array("\n","\r"), array("\\n",""), addslashes($content)).'"'.$style.' });'."\n".'//-->
</script>';

and change it to:

$tipScript = '<script type="text/javascript"><!--'."\n".'JQuery("#bfLabel'.$mdata['dbId'].'").qtip({ position:{adjust: { screen: true } }, content: "'.str_replace(array("\n","\r"), array("\\n",""), addslashes($content)).'"'.$style.' });'."\n".'//--></script>';

That should do it.
