Different icon if running in dev mode


When developing / contributing to a package I often run two instances of Atom at the same time, one in dev mode, the other one in normal mode to edit in. It would be nice if the icon could have a slight indication that this is the Atom running in dev mode, making it easier to distinguish between them when using CMD+Tab.


Here is what we do when developing Atom.

  • Open Atom in production mode for editing
  • Open a Dev window of Atom for testing using atom --dev from the command line or pressing cmd-shift-O.
  • You can tell if the window is in dev mode by looking at the status bar, it contains a little red square.


Yeah, I know that, what I meant is the app icon in the application switcher.
