I think they meant diff-hl.

And make them in Emacs!

Why wait? Unless Mickey has changed his policy but I have received each new release for free after my purchase.

I presume you are speaking of browser bookmarks. I simply use an org file where each bookmark is hyperlinked. I will add this file to Emacs bookmarks as suggested already in this thread and then I’m thinking I could use embark-act to open in my browser from the minibuffer.

Does there need to be?
