Chrome extension pop up windows always on top

google-chrome, google-chrome-app, google-chrome-extension

Solution

Look at this article: http://www.chromium.org/developers/design-documents/extensions/proposed-changes/apis-under-development/panels

Enable using panels here: chrome://flags/#enable-panels

Here is the code I use to create a panel:

let window_id;
chrome.browserAction.onClicked.addListener(()=>{
  if(window_id === undefined){
    chrome.windows.create(
      {url:'panel.html', type:'panel', focused:true, width:150, height:162}
      ,_=>window_id = _.id
    );
  }else{
    chrome.windows.update(window_id, {focused:true});
  }
  chrome.windows.onRemoved.addListener(_=>_ === window_id? window_id = undefined:3);
});

Problem

I've developed a little chrome extension for personal needs. But there's something in the user experience I don't like, the pop-up containing the application automatically closes when it loses the focus. I would like to control the closing behaviour and/or create an always on top popup, I've tried to find my way on Google, Chrome dev forums and API ref but can't find a way to accomplish that.
