chat-popup di mineland

An extension to make web chat messengers be more compact friendly for popping in and out of the desktop.
Compact in this form means a small (preferably vertical) window. It modifies a small-ish portion of the page to make it work on this format.

To toggle the layout to the original form, use the icon that gets inserted into the page.
Currently supports:
-Whatsapp

Suggestions for other websites would be appreciated, but currently i got plans for Discord and Facebook Messenger

This is my first extension as well, so feedback on what breaks would be appreciated.
