Ya, ARC is a pretty good one! Have you heard how the developer is handling the announcement of the shutdown of Chrome apps in 2017? Curious if they'll hop on the Electron bandwagon too.
As an author of the ARC. I'm considering using electron and move to native apps and discontinuing Chrome integration. But right now I'm not focusing on it. At the end of last year when I started moving the old app to new packaged apps platform I already knew that some changes are necessary and I started to modularize the app into web components (using Polymer framework) to be able to relatively fast move to another platforms with minimal change in the code. So UI components are using web only features, app logic only javascript and non-chrome related APIs and finally Chrome related components that can be easily replaced by other platform's implementation. So eventually (this is ongoing task) I'll be able to move pretty much any web environment.
