How do I edit an existing plugin? EG: To edit functionality.

Go to Plugins & Products > Plugin Manager > find he plugin and click Edit > edit and Save.

I see "uninstall code" and "install code" but how do I edit existing code? Can you give me a sample demo.

You are not looking at the right page. I said the Plugin Manager page, not the Manage Products page.
