Is there any way at present to get access to a detached Dev Tools window so we can programatically manage the location and size?
Not built into the Atom API, no. If there is a standard Chromium way, I’m sure it is probably still available.
Node webkit has this feature. Actually, they return a reference to the window when you run “openDevTools()” which is an intuitive API design IMO.
Probably something we can look at adding later on to this framework…?
