I have a small suggestion for AdRotate.
If you leave the title of a widget empty, the outputted code will still display the heading tags, which, when empty, might not be desirable.
Therefore I propose that future releases change the following lines of code 20 and 99 to be changed for the following,
from
echo $before_widget . $before_title . $options['title'] . $after_title;
to
echo $before_widget;
if(!empty($options['title'])) {echo $before_title . $options['title'] . $after_title;}
I can also see that others have talked about unlimited number of widgets, I will see if I can figure out how to add this, and if so, share the code in this forum, for those who might wish to add that hack to the plugin.
Cheers,
Olaf
