@lkingsella Open your app, press CMD + N (or CTRL + N on Windows) to open a new window with the same profile, then install the 1Password extension.

@nhodges, THANK YOU!

Thank you! Just what I was looking for. Now I can use WhatsApp web as an 'application'.
I've used this script to make a GUI: https://github.com/victor-torres/quickwebapp.

Is there a way to get notifications & app name in the menubar working ?

Ditto both these questions.

1. Click on the 'Raw' button. Download and save the file to your Desktop.
2. Open Terminal.app
3. In terminal prompt, make the file executable by running the following command (copy paste the command and hit return key)
   chmod +x ~/makeapp.sh
4. Execute the script
   ~/makeapp.sh

Great script! But how do I prevent links to open in that new app instead of the standard chrome profile? If all links I open in my new Gmail app open there instead of my browser that kind of defeats the purpose of such an app. Any ideas? Can I force links to open in my standard Chrome profile?
