This package provides a process manager UI for Electron applications.
It opens a window displaying a table of every processes run by the Electron application with information (type, URL for webContents, memory..).
:warning: For @electron>=3.0.0, <7.x, use version 0.7.1 of this package.
For versions >=7.x, use latest.
It can be useful to debug performance of an app with several webview.
It's inspired from Chrome's task manager.
