Opening external page in sidebar

[houshuang]

This issue made me think that this is something that could possibly be done by this extension... Ideally I would like even the option of running the webpage through a readability filter, like this https://github.com/masukomi/arc90-readability (which would make webpages work much better in narrow formats). Not sure if this is possible with security features though.

this would be neat!
