Run as app window, instead of tab

[timkinnane]

Hi, firstly this is great, thanks!

I prefer to use some services like Google Keep as their own self-enclosed app windows, so they don't get lost among the tabs. I've edited my local copy of this workflow for Keep to run a shell script to launch it as a chrome app, e.g.:

"/applications/Google Chrome.app/Contents/MacOS/Google Chrome" --app=https://keep.google.com

Thought I'd offer that suggestion for anyone finding this. Maybe you could wire up an argument to toggle the behaviour and allow both in this workflow, like keep or keep tab?
