This service turned very popular, the problem with this was you need to have a web browser tab open or sometimes a separate new window for the Web Interface.
So, I discovered this app while browsing GitHub for interesting projects, I discovered ChitChat an open source, app available for Mac.
I tried it out and found it interesting and was the right solution for this problem.
This application lets you have WhatsApp Web as a Mac app and integrates well with the Notification Center and lets you access some options from the Apple menu bar.
The app is under active development, so there might be a few bugs, and certain features might not be currently completely functional like the media upload option
