Steps to reproduce the problem:
I am new to chrome extension development and I am not sure if this is the right forum for posting my dis-content about developing the chrome extension. In case it is not the right forum, please help me to navigate to right one.

I am bit frustrated to find out the process of enabling and disabling the page action icon for chrome extension. Sending a message to background page/script and then showing the icon makes it two step process, nonetheless it is confusing for beginners. In my opinion, control for enabling the icon (which in turns controls enabling/disabling of extension) is always with control script which logically make much sense rather than giving to background script (please understand I am not talking here about implementation perspective but business or logical perspective). In my support, I have found many questions (some having confusing answers) which support my conclusion.

Also, I got to know that page actions has been moved out of omnibox which was unprecedented for me. I personally would like to see them back in, similar to bookmark, password or language translation functionality.

What is the expected behavior?
