oh, excellent! thank you. I have a janky custom setup, so jetpack doesn’t really work too well, but this looks like it would have been perfect.
in the end I solved the appended link problem by trial and error, manually editing some of the plugin code. a toggle to switch bluesky sharing on and off would still be great, but I appreciate that the developer has a lot of projects in the air and this isn’t necessarily something he can prioritize (though it’s a neat, useful app).
