Just happened to know about this plugin while reading some comments somewhere...
So I tried "Clean Options" and it worked perfect. I was able to get rid of 1,5mb (!) of crap remaining from uninstalled and already deleted plugins.
I like your links to Google. Very convenient if we are not too sure of what the tag is about. To preview the elements before deleting them is also a great idea.
Yes! your plugin "Clean Options" is VERY useful and you should keep updating and promoting it.
I'm sure quite a few guys out there still don't know about it. I will spread the word when I can in some comments...For the moment I already rated with 5 star :-)
THANK YOU for your great contribution to the community!
