The implementation of the series detail page means that it's difficult to send someone a link to a patch within a series - it stays on the same page and loads the patch into it. I'm not sure if we'd have to change it to go to a different page, if that would disrupt reviewing a series then we'd want to avoid that, but it's a bit annoying that I can't just copy the URL for an individual patch and paste it into chat. (I'll accept it if there isn't a best of both worlds solution for this one.)
I've included column "Link" at the Series view where a direct link to the patch is labeled with the patch ID and can be copied or clicked to display the patch detail in a new tab. Fix can be viewed at https://lists.yoctoproject.org/pipermail/yocto/2017-September/037802.html and an implementation example at the staging instance: https://patchwork-staging.openembedded.org/series/6426/
Change is now implemented in production instance.
