Option to close all remote chrome extensions that are open.

I love popping out the chrome extension on my home and work computer, and I can quickly message from there without getting my phone out.

But then I forget to close the extension.  When the extension is open, notifications are automatically dismissed on my phone.

Would be nice to be able to press something on my phone to close all open chrome extensions on other devices. 

Or perhaps an option on the phone to never auto-dismiss SMS, even when dismissed from chrome extension.
