Filter for options page into admin panel

Hi everyone,

As you all know there is a filter in admin panel catalog/product.
Thus you can filter the products and it is easy, clever and very useful. You may filter by product name, by model, by price, etc.

I need a filter like the mentioned above for catalog/option. I mean that I need to be able to search for an option's name and nothing more.
For my suprise there is no filter for options. I think that this is a must functionality, because it is very useful for the ones who use options.

I have bought an extension made by Qphoria - Multiple Options Quantity and now I have a lot of options into my admin panel, but there is no filter for them.

Can you please point me to some solution?
I could not find anything to work into: google, forum.opencart.com, opencart's extensions and some web developer's forums.

My OpenCart version is 1.5.2.1
