I thought of allowing a URL to an icon file but there is a security implication of triggering the installing user’s Mac to access an arbitrary URL which is not always a good idea. Plus the possibility of swapping the image at the URL from a benign one to an abusive one. So I didn’t allow it.
thank you. this is great except it doesn’t work in firefox of course because popclip doesn’t register the url in firefox (which is the fault of firefox not of popclip…) so it becomes rather cumbersome which is a pity because i like goodlinks and use it a lot but i can 't live without firefox.
There is no such thing as category in goodlinks. If you mean tags, when you click the extension icon, goodlinks will popup and you can select the tags and add title, notes.
AFAIK, there is no feature available in PopClip to add a “menu”.
