Make it work without having to press the button
Basically, I would prefer it if this extension ~~worked more like atomic-chrome~~ automatically started "syncing" as soon as I click a text field, and didn't wait for me to press the button. Would you consider adding this functionality or accept a PR for it, if you're not interested in implementing it yourself?

I'll certainly accept a PR to implement such a thing. I suspect it might require changing the coms from xmlrpc to websockets which are bi-directional.
Hi @davorb
I made a new package Atomic Chrome for Emacs which is actually a clone of Atomic Chrome for Emacs. I think it would be exactly what you've been requesting. Please have a try on it.
