I do use org-protocol, and I do have it in my FFX, so I am aware of it. But
sometimes I copy a link from a readme file or a piece of code or elsewhere and
wish to stash it away in a note but not necessary open in a browser. You know,
"todo" to come back later for it :).

Yepp, I am aware, the goal was not to be 100% fool proof. I had experienced
sometimes a couple of characters that Emacs can't dissambiguate, but it is not a
problem and yes, in case of no title it will prompt; the other strategy I used
was to return just url itself or "no description". Perhaps I should revert to
just the url.

Yes, I am aware and completely agree with you!

Luckely I am getting quite old by now and don't visit too many sites or sites of
dubious JS character, so for my needs IDC :).

Miros idea served me well for several years now, I just improved it a bit the
other day to skip prmpting for the URL and used asynchornous download to skip
that slight second or two of delay in some links.

Tell me more here? Can I drag a link from one buffer into a note buffer, or how
can I use it?

Thank you for the answer.
