Rename app
Is there a way to name the app something like Imagemin. Right now (on OSX, at least) it shows up as Atom

Leaving this here for reference in case someone wants to pick it up or I get some extra time.
I believe you can achieve this by adding your own Info.plist, putting it into the Contents directory, and changing CFBundleName to Imagemin
generated default:

Here's an example of an app that is doing that as part of a build step https://github.com/awvessel/vessel
The new electron-packager should solve this. There is a fork with an electron-packager npm script but it is not a working rewrite as it seems and there is https://github.com/imagemin/imagemin-app/tree/next.
Or you can take my latest version and use it with the electron-packager.
