I would need the list of currently opened desktop apps (+ files opened in it) from a Chrome Extension, or at least the active application name (With current focus on the desktop).
Use case : Imagine a chrome extension that would get the list of tabs with URLS (I solved it with Chrome.tabs) and in addition would give the name of the current active app when Chrome loose the focus (idle) : exemple => powerpoint.app / documentname.ppt.
I'm looking for any option, ideally without having to implement a Desktop App that would exchange messages with the Extension. But if this is the only way, any example/experience to do so with Electron (http://electron.atom.io/) or Node-WebKit?
