I really hope so, that's exactly the other thing I need it for. 

So many things to do... :)  

 I was looking at it yesterday. On websites, it works easily. Extension has some limitations. Still working on it. 

 On extensions. Even though I have injected content script into the page. Still don’t see window.nostr. This is the limitation for extensions. Some stack overflow says have tricks. So, looking into those. 

 Please let me know how it goes, allowing extensions to access keys easily will be epic! 

 What could works is, putting into pop up. So I planned to do that.
