Re: Mummi wishlist: API using Message-ID

(Sorry for the misspelling of Mumi in the Subject thread.)

(For the record, reading [1], I discovered [2,3] with similar goals
than Mumi and that the Org-mode community uses public-inbox [4].)

I do not know but public-inbox is doing such thing, isn't it?
I mean, the example with emacs-debbugs, my "custom" function and the

Is it not enough?
The URL,  is it not always ready-to-be-pasted?
The link contains '@' but it works (on my webbrowser at least :-)).

Thank you for explaining.

Okish... CSS/JS is not really my cup of tea.  I will try to rehash
your words when giving a look at Mumi source.
