The Raw Code to extend the Recent Posts Widget

Hello Sir,
What I am looking for, is to extend the default WordPress “Recent Post Widget“. All I really want to add is ability to filter which particular Category I want.

Now, your plugin can do it. But I already have 36 plugins on my website, and I don’t want to add more.

So I seem to be making a kind of tough request from you–Can you help me send me the raw code of this your plugin, which I can add in functions.php and still be able to get the correct function of your plugin?

2.) Or can you send me a code which will extend the default WordPress “Recent Post Widget by adding opportunity to select Category?

Needing to hear from you soon.

Regards
